Estimating the carat weight of gemstones which are already mounted is something which experienced jewellers, pawnbrokers and valuers need to do every day.
Over the past few decades the equipment to assist them has grown increasingly sophisticated but now the AnchorCert Gemstone Certification Service has propelled the process into the 21st century with its Gemstone Carat Weight Estimator App for smart phones.
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 carat weight estimator 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.
The free demo version which is currently available for Android phones shows how easy the App is to use and has 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 – which is eagerly awaited – 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.”
You will wonder how you ever managed without it. The AnchorCert gemstone carat weight estimator – definitely the winner on points…
