Russian Sapphire

Gemologist’s Note
A striking oval with a rare, legible bicolor split: the pavilion divides visibly between a warm golden-yellow zone and a cooler, saturated green, the two tones meeting without muddying into a single average color — something this deposit almost never delivers this cleanly. Just under a carat, the brilliant crown with fancy pavilion keeps both halves of that color story alive in the light, the stone flashing actively from every angle. The stone is eye-clean, with nothing breaking up the face-up view. GFCO confirms no heat, no treatment, Sutara origin; the bicolor character is an in-hand observation.
