Russian Sapphire

Gemologist’s Note
Square step cuts are unforgiving in a different way than long baguettes — the proportions are tighter, and any weakness in color concentrates rather than dilutes. This stone holds up to that scrutiny. The tone is dense and saturated, closer to true emerald-green than the yellow-leaning material typical of this deposit, with a crisp bowtie pattern through the pavilion confirming precise, symmetrical cutting. Just under a carat, it still reads as a serious stone rather than a small one. Green this saturated is the exception even within a deposit already known for green — and GFCO confirms it entirely untreated.
