Please identify this crystal

0 votes


This crystal has a very good shiny surface, can see cracks and bruises (I think there might be strong blow), hardness is about 9 and the S. G is 2.70. Indian origin.

My best guess would be corundum, considering the flourescence and the hardness. Corundum is the mineral that ruby and sapphire is composed of, it is found in India, and it can be flourescent. A very beautiful specimen, likely worth a lot of money. What a cool piece!

But the specific gravity explains as quartz

So which one would fit in this
I understand your point about the specific gravity, but I think most of the evidence points to corundum.
