How to Test Gold

1. Rub your item firmly on a testing stone to leave a visible gold streak.
2. Apply a single drop of the matching karat solution onto the streak.
3. If the streak remains, your item is that karat or higher. If it fades, it's lower.
4. Work up through 9K → 12K → 18K → 22K to pinpoint the exact karat.

How to Test Platinum

1. Rub your item on the testing stone to leave a clear metal streak.
2. Apply a single drop of the platinum solution to the streak.
3. If the streak holds, your item is platinum. If it dissolves or changes, it is not.
