Estimating the carat weight of gemstones which are already mounted is something which experienced jewellers, pawnbrokers and valuers need to do everyday.

In a couple of clicks, the AnchorCert Gemstone Weight Estimator can easily calculate the estimated carat weight of diamonds and gemstones from their measurements. The calculation will use the measurement of the length, width and depth of the gemstone (and the minimum and maximum diameter of round brilliant diamonds).

The carat weight estimator contains a comprehensive database of diamonds and gemstones, as well as a wide selection of shapes and cuts. The App contains detailed information about each individual gemstone, including it’s Specific Gravity, Mohs Hardness and Refractive Index. The App also explains the meaning of those terms. Each gemstone has a colour picture and each shape / cut is illustrated by a facet diagram.

To download the App just visit the Google Play Store for Android phones or the App Store for iPhones/iPads and look for “Gemstone Weight Estimator”.
