Understanding Different Types of Gold

Gold has been valued across cultures for thousands of years. While most people immediately picture the classic yellow metal, gold actually comes in a variety of hues, each defined by its purity and alloy composition. Understanding these differences, not just the color, but also durability and karat levels, helps you better assess gold’s true worth. This article explores the colors, alloys, and properties of gold, and explains how these factors influence its overall value.

What determines the color of gold?

Gold purity is measured in karats, with 24 karats representing pure gold, free of any mixed metals. In this form, gold displays a rich, saturated yellow hue and serves as the benchmark for measuring all other levels of purity.

When other metals, or alloys, are introduced, the color and purity of gold change. Mixing gold with these alloys lowers its karat value, for example, 18k or 14k gold, resulting in a paler, less vibrant yellow tone. The specific metals used also influence the final shade, creating a variety of beautiful colors beyond classic yellow.

Gold purity affects more than just color; it also determines softness and durability. Pure 24k gold is quite soft, making it susceptible to scratches, dings, and bending, which limits its use in everyday jewelry. Instead, it’s often reserved for investment forms like bullion, as well as applications in electronics, aerospace, dentistry, and medical devices. For jewelry, gold is alloyed to improve strength, producing lower-karat pieces that can better withstand daily wear.

Yellow Gold

Yellow gold is known for its classic, warm golden hue. To achieve this color, pure gold is mixed with alloys such as silver, copper, or zinc. The type and amount of alloy used influence the tone, warmth, and durability of the metal. A higher ratio of alloy increases the metal’s strength while slightly lightening its color.

With silver as part of the alloy, yellow gold is generally hypoallergenic and unlikely to cause rashes. It is also mostly tarnish-resistant, making it ideal for everyday wear.

  • 22 karat yellow gold: Approximately 91.7% gold, with the remainder made up of alloy metals.
  • 18 karat yellow gold: Contains 75% gold and 25% other metals, typically copper or silver.
  • 14 karat yellow gold: About 58% gold, with the rest composed of alloy metals for added strength and durability.

White Gold

White gold has a silvery-white appearance, similar to silver or platinum. It is made from alloys such as palladium, platinum, and sometimes nickel or zinc. Thanks to the platinum and palladium content, white gold is known for its durability and scratch resistance. White gold is typically available in 10k, 14k, and 18k.

Since white gold is not naturally white but more of a pale yellow, it is often plated with a thin layer of rhodium to achieve a bright white finish. This plating can wear off over time and may need to be reapplied periodically to maintain its appearance.

Rose Gold

Rose gold is a color that has grown increasingly popular in modern jewelry. Its distinctive pink or blush hue is not natural; rather, it is achieved by mixing gold with a higher percentage of copper; sometimes silver is also added. Rose gold has a romantic, elegant appeal, which has contributed to its growing popularity.

Thanks to the copper content, this metal is durable and well-suited for everyday wear. Additionally, because copper and silver are relatively low-cost metals, rose gold is often a more affordable option compared to other types of gold. Rose gold is typically available in 10k, 14k, and 18k.

Other Types of Gold

As you can see, the addition of different alloys allows gold to take on a wide range of colors, more than most people realize. This versatility makes gold a unique choice for jewelry, available in various hues and karat types with differing purity levels.

  • Green Gold – Achieved by mixing gold with silver and sometimes copper. The green tint comes primarily from the silver content. It can also be made using cadmium, though this alloy is toxic to skin. The proportion of alloys determines the shade of green, which can range from light to deep tones.
  • Black Gold – Created using specific alloys like cobalt or through surface treatments. These treatments can include electroplating with black rhodium, oxidation, or laser treatment, giving the metal a dark, striking finish.
  • Blue Gold – Produced by alloying gold with metals such as indium or gallium, which are melted together to form a new compound. Alternatively, it can be made by heat-treating gold alloyed with iron and nickel, creating an oxidized layer that gives it a blue hue. However, both methods result in a brittle material, making it more difficult to work with than other gold alloys.
  • Purple Gold – Formed by alloying gold with aluminum, most commonly at a ratio of 75% gold and 25% aluminum, qualifying it as 18 karat. This combination forms an intermetallic compound, meaning it is not just colored gold but a new material with distinct physical properties.

Bringing It All Together: Purity, Alloys, and Worth

Gold is more than just the yellow metal most people picture. Depending on its purity and the alloys it’s mixed with, gold can take on a wide spectrum of colors, strengths, and applications. Each variation, from the timeless warmth of yellow gold to the romantic glow of rose gold or the sleek appeal of white gold, offers its own balance of beauty and durability.

These differences in composition don’t just influence color and wearability; they also impact the true value of the metal. Because alloys alter purity, they can shift the worth of gold when refined. The higher the karat, the greater the gold content and intrinsic value; the lower the karat, the more alloy present, resulting in less pure gold recovered during refining.

Understanding these distinctions is key when evaluating or refining precious metals. Recognizing how alloy content and purity affect gold’s overall value ensures transparency and accuracy, especially when reclaiming or recycling materials through the refining process.

Factors that affect precious metal prices

Just like everything in today’s world, a major underlying factor of precious metal prices is supply and demand. When there’s an ample supply of metals and less demand, the price decreases. When supply is low and demand is high, the price increases. While it may seem simple, many factors inside and outside of supply and demand influence fluctuations in the prices of precious metals.

Economic Influences

U.S. Dollar Strength: Since precious metals are priced in U.S. dollars, their prices are inversely related. A weaker dollar usually drives up metal prices, and vice versa.

Inflation & Interest Rates: Metals like gold often serve as a hedge against inflation. Lower interest rates reduce the opportunity cost of holding metals, making them more attractive.

Debt Levels & Unemployment: Economic uncertainty caused by high debt or unemployment can increase demand for safe-haven assets like gold.

Central Bank Stability: Central banks are monetary institutions controlled by the national government or private entities with government authorization. These banks hold precious metals in their reserves alongside foreign currency, bonds, and other low-risk options. They collectively own about one-fifth of all gold ever mined. Since precious metals are in constant demand and can be liquidated quickly, they serve as monetary insurance and provide stability during times of economic uncertainty. This allows central banks to loan or sell these assets to other nations without the credit risks associated with other assets and to profit during economic instability.

Quantitative Easing (QE): A monetary policy where central banks purchase large quantities of financial assets to inject money into the economy—QE encourages investment in higher-risk ventures. This is not physical money printing but digital credits added to a seller’s account. QE can either inflate metal prices (as investors seek safe assets) or depress them if investors pursue higher-risk opportunities due to improved liquidity.

Investment Behavior

Risk Aversion: In times of uncertainty, investors flock to metals as a safe-haven asset. When confidence returns, funds often shift back into stocks or bonds.

Exchange-Traded Funds (ETFs): ETFs and mutual funds allow investors to gain exposure to metals without physically owning them, directly influencing demand. These funds are securities that hold the metal and issue shares that investors can buy and sell, similar to stocks.

Political Factors

Political Stability: Market analysts watch elections, policy shifts, and regulation changes for potential impact on precious metal markets. Unpredictability and revolts can impact the global economy, increasing demand for safe-haven assets.

Geopolitical Tensions: Wars, trade disputes, and instability can drive investors toward metals as a safe haven asset.

Tariffs, Sanctions, and Trade Policies: Restrictions on major producers affect supply and prices, while new trade agreements can ease access and shift pricing.

Understanding these key factors and their involvement with the precious metals market can provide insight into better predicting market fluctuations and improving your investment strategies. Taking all that into account, some precious metals have other unique factors that can affect their worth—including the environmental and economic impact of recycling practices. Learn more about how recycling precious metals impacts the environment.

Gold (AU): Timeless Value

Gold stands out as a tangible, universally recognized store of value. Its scarcity, permanence, and historic status as a financial safe haven make it the go-to investment during times of crisis, including diminished currency values, inflation, and overall economic turmoil. When confidence in other financial assets declines, the value of gold rises.

Key Price Influencers

Supply vs. Demand: Unique in that new supply is small compared to total existing stock. Annual mining adds only 2–3% to global supply, making prices more responsive to changes in demand rather than production levels.

Market Demand: Jewelry (50% of yearly demand), industrial applications, and investment channels like ETFs all affect pricing.

Cultural Demand: Particularly strong in China and India, where gold serves not only as fashion but also as a symbol of wealth. Events like the Indian wedding season or Chinese New Year celebrations create predictable surges in demand.

Industrial Use: Though used in smaller quantities, gold’s conductivity and resistance make it indispensable in electronics and medical devices.

Silver (Ag): The industrial Powerhouse

Industrial Applications: Silver is used for its high reflectivity, electrical, and thermal conductivity. These attributes make silver vital in electronics, solar panels, radio frequency identification, water purification, LED chips, medicine, and more.

Gold-Silver Ratio (GSR): Traders monitor this ratio to assess relative value. When gold spikes, silver prices often rise. A high GSR means gold is more expensive compared to silver; a low ratio implies the reverse, influencing trading decisions.

Technology Trends: Growth in renewable energy and tech applications continues to elevate silver demand.

Gold & silver can go hand and hand, refining it can play a crucial role in the recycling process.

Palladium (pd): Auto Industry Dependent

Catalytic Converters: Around 85% of palladium goes into vehicle emissions control systems.

Electric Vehicles (EVs): As EV adoption rises, palladium demand could decrease since EVs don’t use catalytic converters.

Clean Air Standards: Growing global emissions regulations (e.g., in China) continue to drive palladium demand in traditional combustion vehicles.

Market Volatility: Like other precious metals, palladium is sensitive to market instability, trends, and supply disruptions. Its uses span jewelry, dental and medical equipment, and various industrial applications.

Want a deeper look into how palladium is refined and what drives scrap value? Explore our full guide to palladium refining and recycling.

Platinum (Pt): Dual Demand Metal

Platinum shares some uses with palladium but has a broader demand base.

Key Price Influencers:

  • Auto Manufacturing: Also used in catalytic converters, though less than palladium in recent years.
  • Jewelry Industry: Particularly in China and India, platinum jewelry demand can significantly influence prices.
  • Industrial Uses: Platinum is critical in the chemical, medical, and electronic industries, maintaining a stable base demand.
  • Market Substitution: As palladium prices have risen sharply in recent years, manufacturers have started substituting platinum where possible, affecting its demand.

Future Trends To Watch

Understanding emerging developments can help you anticipate market changes:

  • Technology Innovations: Advances in renewable energy, the auto manufacturing industry, electronics, and battery technology could reshape demand, particularly for silver and PGMs (platinum group metals).
  • Political Factors: Monitor political stability, geopolitical tensions, and trade policies, including tariffs, as these factors influence precious metals markets by affecting supply, demand, and investor confidence.
  • Green Economy: As governments and industries adopt sustainable technologies, demand for metals used in solar panels and clean tech will increase.
  • Economic Forecasting: Economic growth predictions, inflation expectations, and geopolitical developments will continue to guide investor behavior in the metals market.

Final Thoughts

Precious metals remain a cornerstone of diversified investment strategies. Whether you’re focusing on gold’s safe-haven appeal, silver’s industrial utility, or the unique roles of palladium and platinum in modern manufacturing, staying informed on these driving factors can give you a competitive edge.

By monitoring macroeconomic trends, policy shifts, and technological advancements, you can make more informed, strategic decisions when investing in precious metals.

The Evolution of Gold Refining Technology: How Modern Equipment Has Changed the Industry

For thousands of years, humans have been fascinated by gold. Not just for its beauty, but for its enduring value and utility. The process of gold refining dates back to ancient civilizations like Egypt, Mesopotamia, and the Indus Valley, who pioneered early methods to extract and purify gold from raw materials. Over time, gold refining has evolved from basic fire-based techniques to advanced chemical and electrochemical processes that achieve exceptional levels of purity.

In today’s world, gold refining plays a critical role in global industries such as electronics, jewelry, and finance, and in environmental sustainability. Modern refiners focus on reducing toxic byproducts, reclaiming precious metals from waste, and implementing eco-friendly technologies to ensure cleaner, safer refining practices.

This blog explores the evolution of gold refining, from ancient methods to today’s advanced, eco-friendly technologies, and how each era shaped the innovations we use today.

Looking for the best precious metal refinery?

3,000 BCE – 500 BCE: The Beginnings of Gold Refining

The ancient civilizations of Egypt, Mesopotamia, and the Indus Valley pioneered early gold refining techniques. They were the first to use clay pipes and furnaces in smelting and employed placer mining to extract gold from riverbanks, collecting particles found in sand. Through the use of fire and basic tools, they began separating impurities from gold, marking the birth of gold refining. These cultures were revolutionizing the process by using heat to extract gold from stone and rock, a groundbreaking advancement in early metallurgy.

Notable techniques included:

  • Cupellation: A fire-assay method where a mixture of metals is heated in a porous container, allowing base metals to oxidize and separate, leaving behind purified precious metals.
  • Cementation: A process that uses a reducing agent, like salt, and heat to isolate and concentrate gold from ore.

Drawbacks: Cupellation was labor-intensive and required precise temperature control, something difficult to maintain without modern equipment.

500 BCE – 500 CE: The Greek and Roman Advancements

The Greeks and Romans advanced gold refining by merging alchemy with early scientific principles. They introduced mercury amalgamation, mixing gold with mercury, then heating it to evaporate the mercury and leave behind gold. This technique laid the groundwork for modern chemical gold refining.

  • Mercury Amalgamation: Enabled the extraction of gold from ore but posed significant health and environmental risks.
  • Acid Refining: Early methods of dissolving base metals with acids helped evolve today’s chemical gold refining processes.

Modern Mitigation: Today, dental offices use amalgam separators to reduce mercury discharge into sewer systems, and many recycling companies specialize in mercury-safe disposal.

500 CE – 1500 CE: The Medieval and Renaissance Shift

Gold refining declined during the early medieval period but saw renewed interest during the Renaissance. The focus shifted toward assaying, the practice of testing gold purity, which remains essential in modern gold refining.

Key techniques included:

  • Touchstone Testing: Rubbing gold on a smooth, dark stone and comparing the streak to known samples to determine purity.
  • Inquartation: Adding silver to a gold alloy to dilute it, making impurities easier to dissolve in acid and resulting in purer gold.

  • Inquartation: Adding silver to a gold alloy to dilute it, making impurities easier to dissolve in acid and resulting in purer gold.

The Industrial Revolution (18th–19th Century)

The demand for standardization and industrial efficiency revolutionized gold refining. Two landmark techniques emerged:

  • Miller Process (1867): Invented by Francis Bowyer Miller, this method uses chlorine gas to react with impurities in molten gold, forming a removable slag. Ideal for refining large quantities quickly.
  • Wohlwill Process (1874): Developed by Emile Wohlwill, this electrolytic method uses an electric current to dissolve impure gold, leaving pure gold to collect on a cathode. It achieves up to 99.999% purity.

These innovations transformed industries such as jewelry, electronics, and currency production, and laid the foundation for modern gold refining practices by enabling the production of pure gold in large quantities.

20th Century – Present: The Modern Era

Modern gold refining has evolved into a high-tech industry prioritizing precision, efficiency, and environmental responsibility. Today’s methods include smelting, electrolysis, and aqua regia refining, which uses a powerful mix of nitric and hydrochloric acid to dissolve metals.

Recent advancements include:

XRF and ICP Spectrometry:

  • X-ray Fluorescence (XRF): Measures emitted X-rays when a material is exposed to high-energy X-rays, identifying its elemental makeup.
  • Inductively Coupled Plasma (ICP): Ionizes samples to detect trace elements with high accuracy.

Eco-Friendly Refining: Some refiners now recycle scrap gold and use bio-based solvents and renewable energy sources, reducing reliance on toxic chemicals and minimizing environmental impact in the gold refining industry.

The Troy Ounce Explained

If you’ve ever dipped your toes into the world of precious metals—whether it’s gold, silver, platinum, or palladium—you’ve probably heard the term troy ounce pop up. But what exactly is it, where did it come from, and why does it matter so much?

Unlike the standard ounce used for everyday items, the troy ounce is a heavier, specialized unit used exclusively for precious metals. And while the difference might seem minor, it plays a major role in how metals are priced, traded, and valued around the world.

In this article, we’ll explore the history, purpose, and continued relevance of the troy ounce in today’s global precious metals market.

What is a troy ounce?

A troy ounce is the standard unit of measurement used strictly for weighing precious metals. Often abbreviated as “t oz” or “oz t,” one troy ounce is equivalent to 31.10344768 grams. A standard (avoirdupois) ounce weighs slightly less—28.35 grams.

The name “troy ounce” originates from the French city of Troyes, a bustling trade center that attracted merchants from across Europe during the Middle Ages. To accommodate international trade, merchants in Troyes adopted a standardized weight system: 480 grains of barley equaled one troy ounce, and 12 troy ounces equaled one troy pound. This system laid the foundation for the British coinage system, introduced by Henry II of England in the 1400s. Prior to this, the avoirdupois system—used for weighing both precious and non-precious goods—was more commonly applied. By the early 1500s, the British formally adopted the troy ounce as the standard for gold and silver. The United States followed suit in 1828, and the troy ounce has remained the global standard for precious metals ever since.

Measuring Units Equivalent to
1 Troy Ounce
Standard Ounce (oz) 1.094
Kilograms (kg) 0.0311
Grams (g) ~31.103
Pounds (lbs) 0.0685
Carats (ct) 155.517
Pennyweights (dwt.) 20

Troy Ounce Vs. Regular Ounce

It’s a common misconception that all ounces are the same—but when it comes to weighing precious metals, this couldn’t be further from the truth. Understanding the differences between these measurement systems is essential for investors, refiners, and anyone entering the precious metals market.

  • 1 Standard ounce = 28.35 grams 
  • 1 Standard pound = 16 oz
  • 1 Troy ounce = 31.103 grams
  • 1 Troy pound = 12 ozt

Why is the troy ounce important?

Standardization: Everyone’s Speaking the Same Language

In a global market, buyers and sellers must use a common unit of measurement. The troy ounce serves this purpose, offering an internationally recognized standard for precious metals. Whether you’re trading in New York, London, or Tokyo, a troy ounce of gold means the same thing—offering clarity and consistency worldwide.

Accuracy: Precision Where It Counts

Precious metals are often traded in small quantities, where even the slightest difference in weight can have a significant impact on value. The troy system was built for this purpose, providing more precise measurements than the everyday avoirdupois system.

Comparability: Making Apples-to-Apples Comparisons

Using the troy ounce makes it easy to compare weights and values across different forms of metal, regardless of origin. This is vital in a fast-moving market, helping investors assess metals accurately and make smarter decisions.

How to ensure you’re getting an accurate weight 

To protect your investment and avoid costly errors, make sure:

  • You have access to accurate tools and proper weighing techniques to check weight in any measurement, when needed.
  • Ensure you understand how the professionals you work with weigh your material.
  • You review product specifications or assay details to confirm the correct unit was used.

Choosing the right refiner 

When deciding to recycle your precious metals, choosing the right refiner is crucial. At Core Scientific, transparency is our priority. That’s why, when you refine with us, you get free access to your customer portal—where you can track your material’s progress, view photos of the weight upon arrival, and access detailed assay and settlement reports that break down your precious metals by weighted troy ounces.

For even closer monitoring, you can opt in to receive SMS updates on your shipment’s status—keeping you informed every step of the way, right at your fingertips.

Troy Ounce Recap: A Small Measurement with big impact

A troy ounce is the standard unit used to measure precious metals like gold, silver, platinum, and palladium. Heavier than a regular ounce, it plays a crucial role in ensuring consistency, accuracy, and fairness in global metal markets.

For anyone investing in or buying precious metals, understanding the troy ounce is essential. It’s not just a quirky historical measurement—it’s a fundamental part of how the precious metals market operates today. Knowing what it is and why it matters helps you avoid miscommunication, make informed decisions, and ensure you’re getting the true value of your metals. Whether you’re a first-time buyer or a seasoned investor, understanding this difference is a small detail that makes a big impact.

Identifying Precious Metals in Your Dental Scrap

Many materials removed during dental procedures contain a significant hidden value. Gold crowns, bridges, and porcelain-fused-to-metal restorations often include recoverable precious metals like gold, palladium, platinum, and silver.  When collected and refined properly, these metals can generate meaningful financial returns while supporting environmentally responsible practices.

Identifying what qualifies for refining and what requires specialized disposal enables dental practices to maximize return value while upholding regulatory and environmental standards.

What Makes Dental Materials Precious?

Many dental restorations contain precious metals such as gold, silver, platinum, and palladium—even if they don’t look valuable at first glance. For example, just because a material isn’t gold-colored doesn’t mean it lacks value. Restorations that appear silver, gray, or partially ceramic may still contain highly valuable metals worth refining. Here’s a breakdown of common dental materials and their valuable components:

Gold Crowns & Yellow Partials: These restorations often contain high percentages of gold, sometimes mixed with other precious metals. They are among the most valuable dental scraps due to their high precious metal content.​

Porcelain-Fused-to-Metal (PFMs): PFMs combine the aesthetic appeal of porcelain with a metal substructure, which may include precious metals like palladium or platinum. Despite the porcelain overlay, the underlying metals can be recovered and refined.​

Extractions with Inlays/Onlays: Extracted teeth that contain inlays or onlays may have precious metals embedded within them.

Buttons & Sprues: These are remnants from the casting process in dental laboratories and often contain concentrated amounts of precious metals.

Bridges: Dental bridges may contain precious metals, especially if they are older restorations.

Turning Dental Waste Into Value

Understanding the hidden value within dental materials is key to maximizing both environmental responsibility and financial return. From high-yield gold crowns to lab remnants like buttons and sprues, many restorations contain recoverable precious metals such as gold, silver, platinum, and palladium.

It’s easier than ever to manage dental scrap responsibly. But when it comes to extracting the highest value from your dental scrap, partnering with an experienced precious metal refinery is crucial.

How to Prepare Your Jewelry Scrap for Refining To Get The Most Value

Looking for the best jewelry refinery?

If you’re a jeweler, goldsmith, or any business who regularly works with precious metals, you’re sitting on more value than you might realize—literally. From broken chains to dust on your workshop floor, your jewelry scrap can add up to significant returns when prepared correctly for refining. Here’s how to make the most of every gram.

Common Scrap Items Worth Refining

Not all that glitters is gold—but a surprising amount is. Here are common items that can and should be refined:

  • Jewelry – Broken rings, chains, earrings, cufflinks, and other gold or silver pieces.
  • Watches – Gold or Silver components are suitable for refining.
  • Bench Sweeps – Tiny filings, dust, and small fragments that tend to accumulate on a jeweler’s bench.
  • Gold or Silver Coins – Old or damaged coins can be valuable refining material.

Preparation Tips:

Proper sorting and preparation not only maximize your payout but also ensure a smoother refining process.

1. Document your Karat Purity: Since refiners pay based on metal content, noting the purities of your items gives you a clearer understanding of what you’re shipping to be refined. While reputable refiners will test and verify the materials, keeping your own records promotes trust, transparency, and confidence in the results you receive.

2. Optional Stone Recovery: If you’d like the refinery to recover your stones, notify your account executive in advance and clearly label your package. This process differs from standard karat scrap refining and may involve different timelines or costs, so clear communication is important to ensure proper handling.

3. Store Separately: To ensure accurate refining and maximum return, always keep materials separated by type. Use dedicated, clearly labeled containers or plastic bags for dust, filings, and bench sweeps, and avoid mixing them with general debris or trash. Karat scrap, low-grade material, and PGM-containing (platinum/palladium) items should also be stored separately.

4. Label, Store, and Ship: Clearly label each container with the material type and karat, and store it in a secure location. Ensure your team, especially cleaning staff, understands that this material should never be discarded.

When it’s time to ship, follow proper security measures: place your material in a container within a container or box, seal all seams with a strong packing tape, and label everything accurately. Always coordinate with your refinery to ensure secure and documented transit.

Don’t Overlook Low-Grade Material

Even your dirtiest corners can be a goldmine—literally. These items might not look valuable, but they often contain fine particles of gold or silver:

  • Polishing dirt and fibers from polishing machines
  • Floor sweeps and used vacuum bags
  • Carpet, floor mats, and chair cushions near workbenches
  • Used paper towels from cleaning tools
  • HVAC and air filters in workshop spaces

Collect these items and store them in clearly labeled bags or containers. While these materials may require more processing, the yield value can surprise you over time.

Although these materials might look worthless at first glance, the truth is quite the opposite—dust, fibers, and even old, dirty carpet from a jewelry shop can contain significant amounts of gold and other precious metals. In fact, we’ve recovered thousands of dollars in value from what many would consider trash. It’s a powerful reminder that in this industry, even the smallest particles can hold hidden profits.

Choosing The Right Refinery: Core Scientific

Every part of your workspace holds potential value. The more intentional you are with what you collect and how you prepare it, the better your refining returns will be.

The next step is finding the right refining partner.

Tips to Avoid Buying Bad Scrap Gold Jewelry: A Guide for Jewelers and Pawn Shops

Looking for the best jewelry refinery?

When you’re buying scrap gold jewelry over the counter, every transaction is a balancing act between opportunity and risk. One good deal can make your day, but one bad piece can eat into your profits and damage your reputation. Whether you’re a jeweler, pawnbroker, or professional gold buyer, learning to assess gold accurately and consistently is essential to protecting your margins and building trust with your customers.

Let’s walk through the essential steps to avoid costly mistakes when purchasing scrap gold—and how to ensure every transaction is based on facts, not guesswork.

Why Buying Scrap Gold is Risky – But Rewarding

Scrap gold buying offers a chance to acquire precious metal at a margin below spot price, often with strong resale or refining value. But with that upside comes risk: fake, plated, or under-karated items are more common than ever, especially with the rise of sophisticated counterfeits. A single misstep can turn a profitable transaction into a loss.

The key? Build a bulletproof evaluation process that you and your staff can follow every time.

Here are 8 essential steps you should take to avoid buying bad scrap gold:

1. Start With a Visual Inspection

Before running any tests, take a close look at the piece. Search for a karat stamp such as “10K,” “14K,” or“18K.” However, don’t rely on stamps alone—fraudulent markings are widespread. Watch for:

  • Discoloration or flaking in high-wear areas
  • A different base metal showing underneath
  • Mismatched stamps on chains and clasps

If something looks off, assume nothing and proceed with further testing.

2. Run a Magnet Test

Use a strong magnet to check the item:

  • No reaction? That’s a good sign.
  • Attracted to the magnet? It’s likely alloyed with ferromagnetic metals—or it’s not gold at all.

While this test won’t confirm purity, it quickly rules out obvious fakes.

3. Perform an Acid Test

An acid test can help you identify karat levels using a test stone and acid solutions. Here’s the catch:

  • Plated items can pass this test if the plating is thick enough
  • It’s not always accurate for white gold or newer alloys

Use acid tests in conjunction with other methods, not as your only filter.

4. Use an Electric Gold Tester

For more reliable results, electronic testers can help you quickly assess karat without damaging the piece. These are especially useful for items like white gold, where visual cues are less reliable.

5. Weigh With Caution

Weight gives valuable clues, but don’t take it at face value; know the expected weight for typical items. Lightweight jewelry may be hollow, plated, or contain fillers that reduce its gold content. Compare the weight against standard benchmarks for similar items and factor in discrepancies before making an offer.

6. Invest in XRF Testing (if available)

An X-Ray Fluorescence (XRF) analyzer is a non-destructive, high-precision tool that provides lab-level accuracy in seconds, reading the exact elemental composition of a piece—without leaving a scratch. It’s especially useful for verifying under-karated pieces or alloys with inconsistent mixes. While the upfront cost is significant, XRF can pay for itself by preventing just a few bad purchases.

7. Document Every Purchase

A clear paper trail protects your business. Always:

  • Take a photo ID from the seller
  • Record karat, weight, and payout
  • Note any unique marks or characteristics

This helps protect your business from fraud and aligns with secondhand dealer compliance regulations.

8. Stay Aware of Common Scams

Beware of:

  • Items marked “14K GP” (gold plated)
  • Foreign stamps that mimic karat marks
  • Gold-filled jewelry disguised as solid
  • Chains where only the clasp is genuine

Bonus Tip: Use a Karat Calculator to Validate Your Price

Once you’ve confirmed the purity and weight, be sure you’re paying the right price. You can use our Free Karat Calculator to estimate the value of scrap gold in real-time based on current market prices. It’s a simple tool that ensures consistency, accuracy, and transparency—whether you’re buying 1 gram or 100.

When it comes to buying gold, it’s not just about what it’s worth—it’s about how confidently you can stand behind every purchase. The more informed your evaluation process, the less risk you carry on your books. A few extra minutes of due diligence can mean the difference between profit and loss.

If you’re processing scrap gold and want to maximize your returns with a transparent, fast, and accurate refining partner, reach out to Core Scientific today. Our team helps jewelers, pawn shops, and gold buyers nationwide unlock the true value of every gram. Request a container, and get started refining your jewelry scrap!
