How Testing Works

  • 1. Rub on the Stone

    Lightly rub the item on the testing stone to leave a small streak. Always test on the stone, never directly on jewelry.

  • 2. Apply One Drop

    Apply a single drop of the matching testing solution to the streak — no acid touches the jewelry.

  • 3. Read the Reaction

    Compare the color reaction to verify purity. Reliable, repeatable results in seconds.
