5.58 ct natural cushion-cut Sapphire, showing a cool, saturated tone that shifts subtly between daylight and incandescent light. Cut to 10.25 x 9.11 x 5.32 mm, the proportions were chosen to balance color and brilliance rather than maximize weight alone. 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.
