Best-Selling Gold & Silver Jewelry Testing Kit
Trusted Nationwide by Buyers, Sellers, and Investors
All-In-One Gold and Silver Testing & Appraisal Kit
Fast. Accurate. Easy to Use.
This professional-grade kit is built around genuine JSP testing solutions, trusted by jewelers since 1980, and designed to quickly determine the karat and purity of gold and silver jewelry, scrap, bars, and coins.
Why This Kit Is Different
Most testing kits use small, imported acids that sit too long and lose accuracy. This kit does not.
• Never imported testing acids
• Made 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 bad readings. This kit is built for accuracy.
Simple Testing Process
Scratch your item on the test stone, apply a drop of the appropriate solution, and observe the reaction. Results appear in seconds using the included color chart and instructions.
