Jewelry Testing Kit for Gold, Silver, and Platinum - Scrap Jewelry Shoppers

Perfect for individuals who enjoy buying, selling, trading, or investing in gold, silver, and platinum jewelry and other precious metals, this set provides all the tools needed to conduct acid testing.

To perform the acid test, simply rub your sample (jewelry or coin) on the testing stone to leave a residue. Then, apply one drop of the appropriate testing acid onto the residue for analysis.

For platinum, the material should retain its bright, white color when one drop of platinum-testing acid is applied. Silver can be tested using a color reader system, with dark red indicating a purity of 90% - 100%, light red or brownish for 80% - 90%, and light green for 65% - 75%.

To test gold, apply a small drop of the solution with the same purity level you suspect your sample to be. If the residue remains unchanged, it matches the purity you tested for. If the acid dissolves the metal, your sample is less pure than expected; try testing with a less concentrated solution.

This set includes six (6) half-ounce bottles of JSP acid testing solutions, two (2) PuriTEST test stones, and detailed directions. Each bottle contains a different solution for silver, platinum, and various gold purity levels (10K, 14K, 18K, and 22K).

Ideal for scrap gold buyers who frequent internet and flea markets, this set is guaranteed fresh, delivered fresh, and shipped quickly to your location.
