Product Description
JSP & GTE Gold, Silver & Platinum Testing Kit
Complete 8-Piece Professional Appraisal 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 matters when testing precious metals, and every bottle is produced to professional standards for consistent, reliable reactions. Each 0.5 oz bottle provides enough solution for hundreds of tests, delivering far more value than many smaller, imported competitor kits.
These compact bottles are ideal for bench work, travel, estate buying, or carrying in a briefcase for on-the-spot verification.
