PRODUCT DETAILS & USAGE:
Gold Testing Solutions (10K, 12K, 14K, 18K, 20K, 22K, 9K):
Simply rub your item on a test stone then apply a drop of the solution onto the gold streak left on the stone. If the streak is unaffected, your material is at least that karat or higher. Use progressively higher karat solutions to determine the exact purity.
TrueAssay Silver Testing Solution:
Simply rub your item on our test stone then apply a drop of the solution onto the silver streak left on the stone. Results are as follows: Bright red = .999 fine Silver. Dark red = .925 sterling silver. Brown = .800 silver. Green = .500 Silver.
TrueAssay Platinum Testing Solution:
Simply rub your item on our test stone then apply a drop of the solution onto the platinum streak left on the stone. Results are as follows: If the streak is unaffected, it is platinum. If the streak dissolves or changes color, the material is not platinum. Palladium will turn red.
