2.74 ct Blue Sapphire - Oval

At 2.74 carats, this sapphire from Nigeria carries its blue color through an oval cut, measuring 9.4 x 7.2 x 5.3 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. Nigeria is an increasingly important sapphire source, much of it fine enough to need no treatment at all. It carries no treatment of any kind, so the color you see is the color that came out of the ground.

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.
