Small stones are easy to overlook, but color doesn't scale with carat weight — and this one has more of it than sapphires twice its size. At 0.65 carats the saturation runs deep, a true green with none of the washed-out lightness smaller stones so often carry. The Russian brilliant-cut crown paired with a fancy pavilion gives it a crisp, checkerboard scintillation that keeps the whole face active in changing light. GFCO reports it as untreated, Sutara-origin natural corundum. Proof that with the right material, size is optional and color is not.
