A 5.78 ct cushion-cut Sapphire. Cut to 9.59 x 6.58 x 5.19 mm, it shows a cool, saturated tone that shifts subtly between daylight and incandescent light. This stone is untreated — no heat, no fillers, exactly as it was mined. With a hardness of 9 on the Mohs scale, the same durability corundum is known for in daily wear. Sold loose, so it's ready for whichever setting you eventually choose.
