Comments on Gem Carat Weight Calculator for Android

★★★★★ A Google User · Dec 10, 2014

Amazing A must tool for every gemologist! Thank you

★★★★☆ Cherie Prinsloo · Sep 4, 2015

Reference chart lacks Specific Gravity Would be 5 stars if the reference charts had specific gravity listed. When testing SG on gemstones to identify them it's difficult to search for the correct SG as you have to check each stones properties.

★★★★★ A Google User · May 24, 2013

Superb Has tons of crystals and shapes to work with! Really wish I'd seen this app before I wasted 14.99 on gemstone weight estimator. C'est la vie! Very pleased

★★★★★ A Google User · Oct 22, 2014

Invaluable tool Very handy for jewelry crafters like myself as it does hundreds of stones beyond typical stuff like diamonds, sapphires etc. Loads of geological info in addition to calculations
