A natural 0.50 carat purple sapphire in an oval cut, completely unheated. At exactly half a carat in an oval, this is a stone with a strong face-up presence for its weight — the oval outline spreads the purple across a broad surface, making the color visible and clear even at this sub-1-carat size. Purple sapphire occupies the hue zone with more red than violet and more blue than pink, giving it a rich, royal character at any size. Unheated status is meaningful even at this weight.

Why Choose this 0.50 ct Unheated Oval Purple Sapphire?

Purple sapphire in unheated quality at 0.50 carats is the format for earring centers, small pendant designs, and accent ring settings where a rich color at a practical weight is the goal. The oval cut maximizes the face-up color display for the half-carat weight, and the unheated status ensures the natural purple-blue balance that heat treatment would modify.
