A 3.3 ct oval-cut Sapphire. Cut to 10.98 x 7.05 x 4.55 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.

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 .

Understanding Carat Weight

See The Size On Your Hand

Approximate gemstone size on a U.S. size 6 finger

0.07 ct 33.10 ct

Carat (ct.) is the standard unit used to weigh natural gemstones, including the certified sapphires, rubies, emeralds, and other loose gemstones in our collection, and one gram equals 5 carats. Every gemstone listed on Jamsora shows its exact carat weight alongside its independent lab certificate, so you always know precisely what you're buying.

Matched pairs: when a listing is sold as two stones together, the carat weight shown is their combined total, not the weight of each individual stone.

Carat weight alone doesn't fully describe how large a gemstone will look once set, since two stones of equal weight can appear different sizes depending on their cut and proportions. For a more reliable sense of a stone's visual size, check its millimeter dimensions (length × width × depth), listed on every product page alongside its carat weight and certificate details.
