Goodwill Find / Light Blue Crystal

[Indian Steve]

Hello, My name is Steve and I am an addict! I can't pass up a cool rock even if I am the only one that thinks it is cool. This was in a 59 cent bag of rocks at Goodwill. Very light blue crystal in host rock. Any idea what it is? Thanks Steve

Can a knife scratch it? Try in an area not visible. Might be feldspar, although that'd be an unusual colour. Calcite is also possible, flourite as well.

Pink rock is granite, blue is quartz...

I guess flourite

Good. Since a knife can scratch it, we're down to calcite and flourite.

A drop of acid (i.e. vinegar) will settle which one it is. Calcite will bubble and fizzle, flourite will not.
Just wash it off with water afterwards.

Flourite it is! No bubbles, No Fizzle. I was hoping for blue diamond but for 59 cents, Flourite is very cool. Thanks!!!
