help identifying crystals

[RussCA]

My brother found these crystals out on Arizona. We are wondering what they are and if it's worth finding more

Any chance of getting a clearer pic? Welcome to Tnet

Possibly some amethyst? Maybe fluorite for some. If you have any quartz points try and scratch them, that could differentiate between fluorite and quartz.

Possibly Fluorite if fairly soft, 4 to 5 on the Mohs Hardness Scale. Impure Sodalite or impure Lapis Lazuli if somewhat harder, 5 to 6 on the Mohs Hardness Scale.

I'd say flourite gets my vote.

Thanks for your help guys. It does seem to match up with the properties of fluorite best
