1.00 ct Green Sapphire-Color Change - Cushion

At 1 carats, this color-change sapphire from Sri Lanka carries its green color through a cushion cut, measuring 5.1 x 5.9 x 3.7 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. Sri Lanka has produced fine sapphire in every color for two thousand years, prized for transparency and life in the stone. It is wholly untreated, its color finished by geology rather than by any furnace or enhancement.

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.
