Product Details

The Large Gold Test Stone from Eurotool is a natural stone cut to a generous 6" x 4" size, ideal for professional gold testing in a jeweler's bench or assay station. Gold test stones—also known as touchstones—are used to assess the karat or purity of gold alloys by observing the streak left when metal is rubbed across the stone's fine-grained surface. The larger format of this stone provides ample working area, allowing multiple test streaks to be compared side by side without crowding.

Features

  • Natural stone construction for reliable, professional-grade gold testing
  • Generous 6" x 4" surface provides ample room for multiple simultaneous streak comparisons
  • Fine-grained surface texture delivers consistent, readable test results
  • Suitable for use with gold testing acids and test needles
  • A staple tool for jewelers, assayers, and precious metal buyers
