Is it a diamond?


Recommended Posts

Scratching glass is a terrible way to test a stone.. Glass only has a hardness of 5.5 on the mohs scale.. CZ is about an 8.5, sapphire is around a 9 and diamond is a 10.. So even a CZ will scratch glass..


If you look inthe FAQ section of the forum you will see some basic tests you can try at home..

Of course it isn't mine. I would never keep something like this. I just wanted to know if the stone may be valuable. If so, I will go about finding the owner. Thank you for your replies. After seaching for information and examining the stone, I don't think it is a diamond. I may take it to my jeweler just to be sure.
