Complete JSP & GTE Gold, Silver, Platinum & Diamond Testing Kit
Professional 12-Piece Appraisal System
Take control of your jewelry buying, selling, 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 results. 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 kit combines precious metal verification, diamond testing, magnification, and appraisal tools in one comprehensive setup.
