About this item

The Presidium Gemstone Dial Gauge (PDG) is an innovative, industry-leading analog tool designed for jewelers, gemologists, and gemstone enthusiasts who need fast, accurate measurements without hassle. This easy-to-use device measures gemstone dimensions from 0.0 to 23.0mm with precise 0.1mm resolution and converts those measurements directly into estimated carat weight for round brilliant-cut diamonds—eliminating the need to remove stones from mounted jewelry. The PDG stands out as the only analog gauge in the industry that combines millimeter measurement with direct carat conversion, while also featuring an inner scale for US ring size measurement. Its clear and intuitive dial display ensures effortless readability, making it ideal for both professionals and beginners. Built with durability in mind, the PDG incorporates a patented anvil and a non-metallic, lubrication-free rack and pinion system that minimizes wear and preserves accuracy over time. The smooth slider mechanism enhances ease of use, while its lightweight, compact design makes it perfect for use anywhere—no batteries required. Each unit includes a protective carrying case, a gemstone weight estimation table, and an attachment for measuring high-setting jewelry, providing everything you need in one portable solution.
