WHAT STONE IS IT 💎?

[skyder_g]

HELP! What kind of stone is it? It is very interesting and it has a cool property. I put it on ice and it instantly got cold and I could feel it getting cold. Is it a Diamond?


Thanks!

The photo does not show the crystal structures and the stone is very brutal, it is the the hardness of the stone is like flint

Is it magnetic? Can a knife scratch it? If rubbed on a unglazed piece of porcelain, what color do you get?

Invest in a hardness testing kit or round up the items required. That will go a long way in identifying it and help you learn to identify rocks/minerals in the future. TTC

looks like you took those pics with camera flash, which obscures the clues we need to help identify it.

Can you post new pictures in natural light with good focus? You'll get better help that way
