How It Works
- Put on the included protective gloves.
- Rub the piece of jewelry or metal firmly across the touchstone to leave a streak.
- Apply a small drop of the testing solution to the streak.
- Observe the color reaction — a blue or greenish reaction indicates a non-gold or high-silver alloy; a stable mark indicates genuine gold at the corresponding karat.
Safety Note: The testing solution contains acid. Always wear the provided gloves, work in a well-ventilated area, and keep the solution away from children and out of reach of pets.

Frequently Asked Questions
Q: Can this gold testing kit identify all karat levels of gold?
A: Yes! This kit is designed to test and verify 10K, 14K, 18K, 22K, and 24K gold, as well as silver. It covers the most common karat levels found in jewelry, coins, and bullion, making it ideal for collectors and everyday home use.
Q: Will the scratch test damage my jewelry?
A: The touchstone method is considered a non-destructive testing approach — you rub the metal lightly on the stone to create a small streak, then apply the solution to that streak rather than to the jewelry itself. The piece itself remains intact and undamaged during the process.
Q: Is this kit safe to use at home?
A: Yes, when used as directed. The kit includes protective gloves to shield your skin from the testing solution. Always work in a well-ventilated area, keep the solution away from children, and follow the included instructions carefully for a safe testing experience.
Q: How do I interpret the color reaction results?
A: After applying the testing solution to your metal streak on the stone, watch for a color change. If the streak turns blue or greenish, the metal is likely a non-gold alloy or heavily silver-based. If the mark remains stable and gold-colored, it indicates genuine gold. The reaction is quick and easy to read visually.
Q: How much solution does the kit come with, and is it refillable?
A: The kit includes one 10ml bottle of testing solution. This is sufficient for many tests. Replacement solution can typically be sourced from jewelry supply retailers if you need to replenish it after extended use.
