This is another 1 but I have broken a piece off this 1 to try and get a better idea of what it could be. Its about 110mmx 80mm
This is the bit I broke off
Hi :)
Could someone help me identify this? I was told by the person that gave it to me that its a sapphire but I would just like to know for sure :) It is around 180mm x 140mm
Thanks in advance
