JSP & GTE Gold, Silver & Platinum Testing Kit

10-Piece Professional Acid Test Set

Verify the karat value and authenticity of gold, silver, and platinum with genuine JSP & GTE testing solutions trusted by professionals since 1980.

JSP acids are manufactured in the United States and are never imported. Freshness and consistency matter when testing precious metals, and every bottle is produced to professional standards for reliable, repeatable reactions.

Each 0.5 oz bottle is approximately three times the size of many small imported competitor bottles and provides enough solution for hundreds of tests, delivering true long-term value.

Simple 3-Step Testing

Make a small scratch on your test stone using the item being tested.

Apply a drop of the appropriate testing solution to the scratch mark.

Observe the reaction and compare to the included color chart to determine purity.

Fast, accurate, and professional results.

Note: This kit does NOT include a test stone.
