Gem Carat Weight Calculator for Android
So far the best app for gemstones I've found. What I would like to see in gem data sheet is values and answers for double refraction, dispersion, pleochroism and fluorescence. Also a nice feature would be to know what mineral families different gems belong to, like quartz group. Comparison chart has a bug. Shows the same specific density for both gems as the lower one has. I've not tested the calculator yet but I'm impressed with the variety of faceting designs.
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 must tool for every gemologist! Thank you
Very handy for jewellery crafters like myself as it does hundreds of stones beyond typical stuff like diamonds, sapphires etc. Loads of geological info in addition to calculations
Thankx so much.
Accurate calculations, also packed with crystal data. Definitely worth purchasing
Good app, i like it
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
Accurate Good app, i like it
