Amethyst or something else?

[Lost&Found]

I picked up this today at a TS and think it is all Amethyst but I am not a mineral expert. When I shine a led light into the very dark areas it penetrates and illuminates purple. It's 3"x4"x3" and weighs about 2 1/2 lbs.

Any guesses or experts care to comment

Darn sure pretty.

Might be Flourite.

I would say Flourite too.

Fluorite due to the crystal type. Note the square shape. Very nice however.
