Testing Stone in Wooden Box

Precision testing doesn't require compromises. Our gold testing stone is an essential tool for jewellers and retailers who demand accurate results without risking damage to precious pieces. Simply rub the stone across your gold item to remove surface plating, then apply your testing acid to the stone rather than directly to the metal. This proven two-step method reveals the true gold content while protecting your inventory from acid discolouration and spoilage ensuring that tested pieces maintain their pristine condition.
