0.94 ct Blue Sapphire - Oval

At 0.94 carats, this sapphire from Nigeria carries its blue color through an oval cut, measuring 6.3 x 5.3 x 3.8 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. Its color was brought up by heat, a legitimate and accepted practice that the trade discloses and we disclose here.

No two of these line up the same way on color, cut, and origin at once, which is what makes choosing this one feel deliberate. Hand-selected and photographed by Caveman Gems in good light, shown as honestly as a screen allows.
