The Complete PuriTEST Jeweler's Hand Tool Kit contains all of the necessary components in the arsenal of a jeweler, smith, or collector. Kit includes 6 bottles of PuriTEST Acid Solution, 5 PRO Test Stones, a Culti Diamond Tester Series II, a PuriTEST 30x Scale Magnification Loupe, and 10 Stainless Steel Files. The set of 6 PuriTEST Acid Solutions has acid for testing 10K, 14K, 18K, 22K, Gold, Silver, and Platinum. The 2x2 PRO Test Stones come in a set of 5, will not damage jewelry, coins, bars, etc., and are made with high quality materials and rubber backing to ensure the most life out of each stone. The Culti Diamond Tester Series II emits audible sound & displays a green light for an easy, accurate reading. If the stone is fake (i.e. Crystal or other simulants such as Cubic Zirconium) there will be no reaction. Buzzing indicates when the tester touches metal rather than stone (i.e. testing diamonds on a ring or bracelet). The PuriTEST 30x Scale Magnification Loupe is crafted with professional grade optical lenses, wrapped in a stainless steel housing, and delivered with a fine quality carrying case. The 10-pack of Files are made with Stainless Steel and crafted for long use.
