Specifically designed to accurately verify the gold content in jewelry and precious metal items—providing a quick and reliable way to assess purity.
The testing solution reacts chemically with the metal, producing an color change based on the gold's purity—simple to interpret and easy to use, even for beginners.
Ideal for testing a wide range of items, including gold and silver jewelry, antique pieces, collectibles and scrap precious metals—for jewelers, pawn shops, and collectors.
Effectively tests various gold purities including 10K, 14K, 18K, 22K, and 24K, as well as silver and other precious metals—offering a versatile and dependable solution for all your metal verification needs.
Apply a single drop of the testing onto the stone or metal surface: genuine gold will remain unchanged and adhere to the test stone, while fake or low-karat gold will dissolve or turn blue, clearly indicating inauthenticity.
