Not bad overall... Catalog of gemstones are not complete, but it contains a lot of gemological data such as specific gravity. Would be nice to include identification such as spectrography data (absorption) along with the gems Refractive Index.
The information in this app is dare I say complete. I would do well to remember it all. An excellent well organized with a lot of time and effort. Love this app

Great reference, a few bugs Excellent mineral data entirely consistent with other mineral reference books. The search problem someone is having is because it does not accept search with a capital letter. This should be fixed. Also the phone's back button exits the app so you have to use the onscreen app. This should be fixed. Otherwise excellent. Crystal structure with miller indices for cleavage would be nice.
