1.23 ct Blue Sapphire - Cushion

At 1.23 carats, this sapphire from Nigeria carries its blue color through a cushion cut, measuring 7.4 x 5.2 x 3.5 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. It is GIA-certified, and the report is available to view.

Its exact combination of color, cut, and origin is its own, the kind of center stone you choose on purpose and build a piece around. Hand-selected and filmed by Caveman Gems in good light, shown as honestly as a screen allows.
