As cited in previous comments, many specific errors...here's another...use of sphalerite "jewelry" !...how about zinc production and galvanizing. App to be trusted only in a very limited way.

Useful only as a narrow the field tool. Do not take results as gospel. Also, let the different terms for non-metallic lustres enter your life! Vitreous, silky, adamantine are far more useful!

Only 29 minerals. And as stated by previous comments. ... some properties are off or not completely correct.

Biotite mica is not yellow.

So..., fun stuff but statements like dolomite is pink is totally WRONG! Dolomite CAN be pink but not always. There are a number of these inconsistencies. If you are a serious mineralogist or seriously interested in the subject visit the MinDat. - Carl Harris
