1.57 ct Blue Sapphire - Cushion

At 1.57 carats, this sapphire from Sri Lanka carries its blue color through a cushion cut, measuring 6.9 x 5.7 x 4.4 mm.

Sapphire is corundum, one of the hardest materials in the gem world after diamond, and it comes in every color the species holds except the red the trade reserves for ruby. It is entirely untreated; no heat, no enhancement, the color exactly as the earth made it.

A single natural gemstone with no duplicate behind it; once it is set or collected, there is no other. It will outlast everyone who owns it, which is most of what an heirloom really is. Hand-selected and filmed by Caveman Gems in good light, shown as honestly as a screen allows.
