Gem

I got this from beach and I really want to know what it is. Iam literally stumped because I am not getting any clue that what could be this . And one more notable thing is that this rock is super solid and hard unlike its appearance

So this is what I get. Now I don't know if quartz have actually scratched its surface or it is quartz powder.

And I think another test is heating test. If this stone breaks in 10 minutes after constant heating on high temperatures then it would not be a sapphire. Anyways I will try both methods.

these are the same black inclusions that my sapphire has does it lower the quality?

Yes iam understanding what you are trying to say. I have recently checked that it was more harder than quartz and porclain/ceramic tile. I think it is a very low quality sapphire because it does not have any cleavage.

Iam not sure which sample you are talking about?

Are you talking about these photos or my specimen?

Yes I think it needs some polishing. But i think all rough uncut sapphires looks like this

I think this is what an exact raw sapphire looks like.

Is this a raw sapphire?I got this from a mountain.
