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.
Does not work The app requires a sizable databse download that takes longer than 15 minutes and by the time its done you can no longer refund it. If you touch the screen while its dloading you have to start over. once it is properly installed however it is a very good app
