Product Description
GTE & JSP Gold, Silver, and Platinum Jewelry Testing Kit
10-Piece Professional Appraisal Set
This easy-to-use appraisal kit is built with genuine JSP testing acids, trusted by jewelers since 1980, and designed to accurately determine the karat and purity of gold, silver, and platinum jewelry, scrap, bars, and coins.
Why JSP and GTE Acids Are Different
Most testing kits rely on small, imported acids that sit too long and lose accuracy. This kit does not.
• Never imported testing acids
• Manufactured in the USA by JSP, a trusted name since 1980
• 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 matters. Old acid gives false readings. This kit is built for accuracy and repeat use.
Simple Testing Process
Scratch your item on the test stone, apply a drop of the appropriate testing solution, and observe the reaction. Results appear in seconds using the included instructions and color chart.
