The owner of this multicolored gemstone bracelet wanted a safety chain, not just for the added measure of security, but for the convenience of handling the two ends. Using the old torch soldering procedure would put so much heat on the gold link, one or more of the heat-sensitive gemstones would permanently haze or even fracture.
Amethysts, garnets and citrines are just some of the stones that any bench jeweler should know to keep away from a soldering process. But if soldering is forbidden, what's there to do? Simply crimp some links to keep the gold chain in place?
Golden Crown's micro-welding process fuses the links back into a continuous loop for maximum security and more importantly without ever risking the pretty stones with heat.
