[Published as 12563499] Unheated Kashmir Sapphire 0.400ct Loose Stone
Sapphire, a well-known and recognized gemstone. The mineral is corundum, like ruby, but all corundum that is not red is called sapphire. With a hardness of 9, sapphire is the second hardest gemstone after diamond, and its high toughness and stability make it an easy gemstone to care for. This is a rare unheated Kashmir sapphire.
This is an unheated Kashmir sapphire that was polished in India quite some time ago. At that time, polishing techniques focused on preserving as much of the rough stone's weight as possible, so the cut does not prioritize brilliance as much as modern cuts do. However, you can enjoy the unique charm of an old cut. A GIA identification report is included.
