• Green = .500 silver
• No color / clear = not silver or heavily plated

Frequently Asked Questions

Will this damage my silver?
No. You only test a small streak on a stone — your item itself is not altered.

Does it work on plated silver?
Surface tests can read plating as solid silver. For suspected plated items, file a small notch to expose the base metal and test that streak.

Is a testing stone included?
No — pair this solution with our TrueAssay testing stone for best results.

How should I store it?
Keep tightly capped, upright, in a cool, dark place away from children and pets.

Safety First

This solution contains strong acids. Wear gloves and eye protection, work in a ventilated area, and keep away from children and pets. In case of skin contact, rinse immediately with plenty of water. See the included SDS for full handling details.

Disclaimer

Acid testing is a screening method. For high-value items, confirm results with XRF analysis or a certified assay.
