This innovative gauge accurately measures gemstone dimensions up to 0.01mm and provides instant carat weight estimation for 9 popular gemstone cuts-including round brilliant diamonds-without requiring stones to be removed from their settings. This unique capability saves time while preserving the integrity of mounted jewelry. Beyond measurement, the PGCG offers gemstone identification support by calculating Specific Gravity (S.G.) based on entered dimensions and weight. It then references its internal database to estimate gemstone identity, making it a powerful all-in-one diagnostic tool. The device also features PC connectivity via USB, allowing users to easily transfer, store, and print measurement data. Included software provides a comprehensive reference library of 133 gemstones, including their Specific Gravity (S.G.), Refractive Index (R.I.), and hardness values. Designed for portability and ease of use, the PGCG includes a clear digital display, automatic shut-off after inactivity, and a protective carrying case with magnetic power-off functionality to conserve battery life. Whether in the workshop, office, or on the go, the Presidium Gem Computer Gauge is the ideal solution for accurate gemstone measurement, weight estimation, and identification.\u003c\/p\u003e","brand":"Presidium","offers":[{"title":"Default Title","offer_id":45189771526259,"sku":"WBHDWB000TD5TOU","price":442.32,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0643\/1958\/6419\/files\/71U3m61llvL.jpg?v=1783504549","url":"https:\/\/slickpurchase.com\/products\/presidium-gem-computer-gauge-pgcg-digital-gemstone-caliper-with-carat-weight-estimation-0-01mm-precision-9-cut-identificat","provider":"Slickpurchase","version":"1.0","type":"link"}
