1.66 ct Blue Sapphire - Oval

At 1.66 carats, this sapphire from Nigeria carries its blue color through an oval cut, measuring 7.4 x 6 x 4.9 mm.

Sapphire is the gem form of corundum, second only to diamond in hardness among the classic gemstones, which is why it wears so well in jewelry worn daily. Nigeria is an increasingly important sapphire source, much of it fine enough to need no treatment at all. 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.
