Glass Testing Stone — 6" x 3" with Non-Slip Grip

This glass testing stone is a durable 6" x 3" surface designed for precise karat testing with solutions and test needles. The black glass-like finish provides a stable platform and a non-slip grip for secure use in labs, workshops, or jewelry studios.

Perfect for jewelry studios, educational labs, and serious hobbyists, this surface delivers reliable results with every test. Its rugged construction resists heat and chemicals, while the non-slip back keeps the stone firmly in place on damp benches. The 6" x 3" size balances value and convenience for daily workflows.

  • 6" x 3" size delivers value and convenience for everyday testing
  • Non-slip back keeps the stone securely in place during measurements
  • Durable black surface resists staining and cleans easily
  • Ideal for determining karat value with standard solutions and test needles
  • Lightweight and portable for on-the-go testing

Note: This item is discontinued, but it remains a dependable testing surface for established setups. Add to your order today to secure a ready-to-use solution.
