Demo of App that estimates carat weight of gemstones

The modern tool has been created to help jewellers, pawnbrokers and valuers estimate the carat weight of gemstones, which are already mounted.

In a couple of clicks the AnchorCert Gemstone Carat 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 mobile tool contains a comprehensive database of diamonds and gemstones as well as a wide selection of shapes/cuts. The App contains detailed information about each individual gemstone including its Specific Gravity, Mohs Hardness and Refractive Index. The App also explains the meaning of these terms. Each gemstone has a colour picture and each shape/cut is illustrated by a separate outline drawing.

A free demo version currently available for Android phones shows how easy the app is to use and provides full functionality on a small sample of stones and shapes/cuts. It also provides the user with a preview of the complete list of gemstones and shapes/cuts available in the full version. The full version will be released shortly for both Android and iPhone and can be downloaded for around $20 from the Android Market and the Apps for iPhone store.

Michael Allchin, chief executive of The Birmingham Assay Office said: “We are aware of the changing needs of the jewellery industry that we serve and are always trying to create innovative products and services to help them do business. By investing in the AnchorCert App we have taken a leap into the new age of mobile information and we are confident our customers will find this App incredibly useful. Our own SafeGuard valuers have been trialling it in different formats over the past year and are very impressed. While nothing can ever be as accurate as weighing a loose stone, this is not always possible. We see the new app being of benefit to all jewellery valuers, pawnbrokers and jewellers trading in second hand pieces. It will also be attractive to those who have a personal interest in gemstones.”
