JSP & GTE Gold and Silver Testing Kit

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.

Why JSP Gold & Silver Testing Acids Matter

Most entry-level kits rely on small, imported acids that lose strength over time. This kit does not.

• Never imported testing acids
• Manufactured in the USA by JSP, a trusted industry name since 1980
• Full 0.5 oz bottles, up to 3× larger than many competitors
• Always fresh for consistent, reliable results
• Each bottle performs hundreds of tests

Fresh acid is critical for accurate readings. Old or diluted acid leads to false results.

Simple, Proven Testing Process

Scratch the item on the test stone, apply a drop of the appropriate testing solution, and observe the reaction. Results appear quickly using the included color chart and instructions.
