This 8.13 carat cushion-cut Sapphire shows a cool, saturated tone that shifts subtly between daylight and incandescent light. Cut to 11.41 x 11.25 x 6.69 mm, it's a natural stone, not a lab-grown substitute. This stone is untreated — no heat, no fillers, exactly as it was mined. Because it's sold loose, it can go into a custom ring, pendant, or earring setting — or simply stay in a collection as-is.
