Not topaz! I also thought it would be that, but it isn't :/ragi wrote:Topaz?
Topaz is formed from high temperature fluorine rich waters precipitating in cavities, veins or pigmatities in granites and ryholites.
because of it beging transclucent and blue. It didn't look like it could be any other type of mineral
selenite gypsum. Formed as an evaporite deposit in arid conditions. It's used as the main ingredient in plaster products. What gave it away was mostly the crystal system.. Only so many things with a monoclinic structure, and colorless.

Hematite? Usually of sedimentary origin. Sometimes found in metamorphic rocks from contact metamorphism. Major ore of Iron Because it's shiny silver-greyish and crystalled.

barite? I've seen colorless barite crystals before, so I guess it's really just a memorization thing for me. It's used in the manufacturing of glasses and paints, and also in oil well mud. It can be formed in hydrothermal replacement deposits.
Halite Forms by evaporation of water Main use is table salt Eh... mainly a random guess but the blue color? IDRK

Apatite (for whoever said topaz, that's what I initially said, I always get these two mixed up :[
