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.
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
