How to Test Gold
- Rub your item on the testing stone to leave a visible gold streak.
- Apply a single drop of the karat solution directly onto the streak.
- If the streak remains, your item is that karat or higher. If it fades, it's lower.
- Work up through 10K → 14K → 18K → 22K to pinpoint the karat.
How to Read Silver Results
- Bright red = .999 fine silver
- Dark red = .925 sterling silver
- Brown = .800 silver
- Green = .500 silver
How to Read Platinum Results
- Streak unaffected = platinum
- Streak turns red = most likely palladium
- Streak dissolves / changes color = not platinum

Frequently Asked Questions
Will this damage my jewelry?
No. Testing happens on the stone, not on your item.
Does it work on plated items?
Surface tests can read plating as solid metal. For suspected plated items, file a small notch to expose the base metal and test that streak.
How many tests do I get?
Approximately 400 tests per bottle when using single drops.
How should I store it?
Keep bottles tightly capped, upright, in a cool, dark place away from children and pets.
Safety First
These solutions contain 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.
