JSP Gold 14K & Silver Jewelry Test Acid Tester Kit 10k 14k .999 .925 Sterling Testing Stone Detect
4-Piece Professional Appraisal Set
This easy-to-use testing kit is built with genuine JSP testing acids, trusted by jewelers and metal professionals since 1980, and designed to accurately determine the authenticity and purity of gold and silver jewelry, scrap, bars, and coins.
Most entry-level kits rely on small, imported acids that lose strength over time. This kit does not.
