Frequently Asked Questions
Will this damage my platinum?
No. You only test a small streak on a stone — your item itself is not altered.
How do I tell platinum from white gold?
Platinum will not react to the solution. White gold will dissolve or change color because it lacks platinum's acid resistance.
How do I tell platinum from palladium?
Palladium typically turns the streak red, while platinum leaves it unchanged.
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.
