It can scratch quartz crytal ,I threw it against the wall with great force and there was no visible damage. There are some impurities in the color of red and yellow. Is it corundum?

Corundum can be colorless but it’s rare. Corundum is 9 on the mohs scale. I’m not sure how you could test it. I would think it’s some type of quartz before I would think it’s corundum. Rubies and sapphire are both colored corundum.

Not corundum. Looks like quartz to me.

Does it scratch window glass?

Something to remember about hardness: Numbers are sometimes the average of a range; different varieties of a mineral (e.g. quartz) may be slightly softer or harder than exactly 7.

This would be easier if you would tell us where in India you're finding these. Geography can be a clue.

Also, if you want to accentuate certain colors or impurities, please photograph on a neutral (e.g. white) background so we can see what you're talking about.

Below are a FEW CLEAR minerals found in India with a hardness between 7 and 8. IF the current specimen is not quartz, it may be one of these, but more information and testing would be required.

Danburite​

Iolite​

Dumortierite​

Hambergite​

Goshenite*​

Morganite*​

*Most likely candidates, but I still think it's quartz.

My research indicates that Goshenite are found in tamilnadu, which is where I found it.

IMO, you're going about this backward. I would learn about the minerals in that region and how to identify them, THEN go out in the field and see what you can find.

Yes, that's why I said it's a likely candidate. Everything on that list can be found there.

But that doesn't mean that's what you've got.

What do you think about the yellow color, most of the images of Goshenite has the yellow color and hardness also matches? What do you think
