JSP & GTE Complete Jewelry Testing & Appraisal Kit

Gold, Silver, Platinum & Diamond Professional Set

Take control of your jewelry buying and investing decisions with a complete, professional-grade testing system built around genuine JSP acids trusted since 1980 and precision GTE inspection tools.

JSP testing 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 accurate, repeatable reactions. Each 0.5 oz bottle provides enough solution for hundreds of tests and is significantly larger than many small imported competitor bottles.

This all-in-one 12-piece kit combines precious metal testing, diamond verification, magnification, and appraisal tools in one comprehensive setup.
