3.83 ct Blue Sapphire - Round

At 3.83 carats, this sapphire from Nigeria carries its blue color through a round cut, measuring 9.4 x 6 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.

Few stones reach this combination of size and quality, and fewer still come to market. We will tell you everything we know about it before you decide.
