Need help with possible mineral ID

[jr.nation88]

Student brought this one in, said is grandfather used to mine for it back in the day but was not for sure where. We are currently located in SE Missouri (Bollinger County) but not sure this is the area it was mind. It is very heavy and has a very clear luster to it. Have not had much time to 'play' with it but the hardness is over 5 i know. My first thought was Fluorite but I have never personally seen a specimen like this...almost wanna say glass Any thoughts?

Ok, I'll take a mew at it, lol!
The only stone I know of that is that color is apatite (did I spell that right?).
But, I don't know what it looks like uncut, or if it would come that big.
Fluorite, glass, or apatite? Not real sure, just a guess.

Your thoughts are right. This is glass. I see many people trying to sell colored glass as a natural mineral. This isn't fluorite. Don't burst your students bubble. The cleavage, color and size, this is man made glass

I have a piece of this too. I got mine in Jefferson Co. MO & yup it's glass. I just like the color. It's pretty in the flower bed. My Grandfather worked at PPG & I suppose he picked it up there.

+1 on glass - look for tiny air bubbles to confirm

the students brother brought it again this year (new school year, new class). We read the responses together but he pulled out a few pics of blue beryl. I still have my doubts but some of his pics looked very close. Any thoughts on beryl or are we sticking with glass?

 

[mamabear]

the easiest way to tell if it is glass is to look for bubbles in the material.

Looks like glass. Raw aquamarine glass.
