Professional Gold Testing Kit with Touchstone
This practical gold testing kit includes a portable touchstone for accurate gold purity examination. Apply acid drops to test gold content - real gold remains on the stone while fake gold dissolves or oxidizes blue. Perfect for testing 10K, 14K, 18K, 22-24K gold, silver, and platinum jewelry, coins, and collectibles.
The acid changes color based on purity, making it extremely easy to use. Available in S and L sizes for versatile applications in jewelry making and precious metal verification.
