A natural 1.31 carat green sapphire in an oval cut, completely unheated. Green sapphire is natural corundum colored by iron — the durability of Mohs 9 sapphire in the emerald color family, without emerald's fragility, heavy oiling, or inclusion-compromised clarity. At 1.31 carats in an oval cut, unheated, this stone is sized for center stone use in engagement rings, pendants, and signature jewelry pieces where the green is the entire point.
Why Choose this 1.31 ct Unheated Oval Green Sapphire?
Unheated oval green sapphire at 1.31 carats provides practical center stone weight with natural color status — the oval's broad face-up surface makes the green color fully visible at wearing distance. For buyers who want emerald's color palette with sapphire's durability and treatment-free status, this is the format that most directly delivers that combination.
