Sri Lankan Twin Star Sapphire 3.928ct Loose
Sapphire is a well-known stone. This particular type shows a star effect. With a hardness of 9, sapphire is the second hardest gemstone after diamond, and is also tough, stable, and easy to care for. A penlight was used for the photo. The back of the stone is generally unpolished.
The only person in the world who can cut these twin star sapphires and triple star sapphires is a certain cutter living in Sri Lanka.
