Personal Jewelry Testing Kit - Gold Silver Platinum Acid Test Kit with 6 Solutions & 2 Stones | 0.5 fl oz Bottles

This Personal Jewelry Testing Kit is essential for anyone involved in buying, selling, trading, or investing in gold, silver, and platinum jewelry. The acid test method is straightforward: rub your metal sample on the testing stone to leave a residue, then apply one drop of the corresponding acid solution. Observe the reaction to determine the metal's purity. This kit is perfect for scrap gold buyers who operate online or frequent flea markets, offering a reliable way to verify precious metals.

The kit includes six 0.5 fl oz bottles of JSP acid testing solutions: one for Silver, one for Platinum, and four for Gold (10K, 14K, 18K, and 22K). You also receive two PuriTEST test stones. For Platinum, if the material is platinum, the residue will retain its bright white color after applying platinum-testing acid. For Silver, color changes indicate purity: dark red for 90%-100%, light red/brownish for 80%-90%, and light green for 65%-75%. For Gold, if the residue remains unaltered after applying the guessed purity solution, your sample matches that purity. If the metal dissolves, it's less pure; test again with a lower purity solution.

This imported kit provides the tools to accurately assess precious metal content, helping you make informed decisions. All customs duties and GST are included in the listed price, and delivery is handled via ExpressBox tracked shipping. Get a clear understanding of your metal's value with this comprehensive testing set.
