This 6.43 carat cushion-cut Ruby shows a rich, saturated red that draws the eye even under low light. Cut to 10.42 x 9.26 x 6.53 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.

Add an IGI certificate (+$100.00) This stone doesn’t have a certificate yet. We’ll send it to IGI before shipping; the report confirms it’s natural, states any treatment, and is sent with your order. Adds about 10 business days: ships by instead of .
