Can anyone please tell me if this might be real?

Hi so I have this stone that I obtained from a yard sale and I was wondering if it might be an actual green diamond can somebody possibly tell me if it might be and if it may have any value thanks.

Probably fluorite.

Not a green diamond

 

[Tourmaline]

It’s a lovely and typical fluorite.

Definitely not a green diamond but the color is nice!

100% fluorite - they chisel them out as the crystal planes are octahedral (111) in 4 parallel plains - same as diamond - and you can do the same with diamond (at great cost)
