This JSP & GTE Gold and Silver Testing Kit is designed for fast, accurate results using fresh, USA-made testing acids. Unlike many competitors that sell old or imported solutions, JSP acids are produced domestically and bottled fresh, so you get consistent, reliable reactions every time.

Testing is simple. Scratch your item on the test stone, apply a drop of acid, and observe the reaction to determine karat value or confirm silver. No complicated steps. No guesswork.

Each 0.5 oz bottle is larger than many competitor kits, allowing for hundreds of tests per bottle and better long-term value. These are not tiny sample vials. They’re practical, working-size bottles meant to be used.

The GTE test stone features a rubber backing for stability, making it safer and easier to use on any flat surface without sliding.

Compact, portable, and professional-grade, this kit is ideal for jewelers, resellers, collectors, pawn shops, and anyone who needs dependable gold and silver testing.

A must-have for anyone who values accuracy, freshness, and real-world usability.
