You, like many other jewelers and pawnbrokers, use a stone removal service to either resale gems or diamonds, from jewelry pieces or create new pieces for customers. The best and preferred method used for removal of the stones is called Aqua Regia.
History of Aqua Regia
What you may not know is that this process dates back to 1300 AD. Aqua Regia (Latin for “Royal Water”) was first discovered by European alchemist Pseudo-Geber, when he mixed common salt with vitriol (Sulphuric acid). According to historians, this process was one of the ways that alchemists tried to find the philosopher’s stone. Which interestingly enough, is the legendary substance for turning mercury into gold.
Another interesting fact about Aqua Regia is that during WWII Hungarian chemist George de Hevesy took the Nobel Prize medals of Max von Laue and James Franck and used the process of aqua regia to dissolve them into liquid. He was able to keep them safe from the Nazis on a shelf in his laboratory, and following the war take the gold to be remade into new Noble Prize medals.
Today this process is used in refineries and laboratories to dissolve gold and platinum to extract gems and diamonds from jewelry.
Why is Aqua Regia the preferred method?
There are two main reasons why a jeweler or pawnbroker should make sure this process is used for their stone removal.
- The removal of the stones is done properly without damage to the gems or diamonds
- It reduces the likelihood of losing any of the stone materials
Typically when a refinery handles the stone removal, they have an on-site laboratory. However it’s essential you verify that the refinery handling your stone removal service has a laboratory on-site. Why? Simply because they have the methods in place to securing receive the material, conduct aqua regia, and separate out the stones for safe and secure shipping of the product back to you.
