Gold Testing Stone with Wooden Storage Box
This gold testing stone (touchstone) is an essential tool for testing gold jewellery using acid test kits. Commonly used by jewellers, pawnbrokers, scrap gold buyers, and jewellery repair professionals, the stone allows you to quickly check the authenticity and purity of gold items.
Simply rub the item across the smooth black testing stone to leave a metal streak, then apply gold testing acid to help determine the metal content.
The stone is supplied in a protective wooden storage box, helping keep the testing surface clean and protected when not in use.
