AIGS’s Gem Weight Estimator (GWE) - which is calibrated for use with a wide variety of gem materials - allows users to quickly estimate the weight of a faceted gemstone, based on its cutting style and dimensions.
This information can then be archived - along with a photograph of the stone in question - for future reference.
