JSP & GTE Gold, Silver & Platinum Testing Kit

Complete 6-Solution Professional Set

Test gold, silver, and platinum with confidence using 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 verifying precious metals, and every batch is produced to professional standards. Bottles ship sealed and are typically less than two weeks old to ensure reliable, accurate reactions.

Unlike many low-cost imported kits, these 0.5 oz bottles are approximately three times the size of many competitor bottles. Each bottle provides enough solution for hundreds of tests, delivering real long-term value.
