A brief guide to hallmarking of precious metals.

I work with a range of metals including precious metals such as fine silver (precious metal clay), sterling silver and other silver grades such as Bali and Thai silver. Sterling silver is typically 92.5% silver.

For items with silver content less than 7.78 grams a hallmark is not required for me to legally describe it as sterling silver. Once the total silver content is over that weight then the item must be hallmarked (assessed) for me to legally describe it as sterling silver.

My policy is always to describe accurately the materials I use to create any given piece of jewellery. Technically, I must refer to sterling silver or other silver grades as white metal if there is more than 7.78 grams of silver making up the item and it has not been hallmarked. Non precious metals used will be described as base metal or plated base metal of fine silverplated copper.
