White sapphire is natural corundum that formed without the trace elements that produce color — the same mineral species as blue, yellow, or pink sapphire but entirely without chromophores. The radiant cut at 1.73 carats produces a stone with strong face-up presence and a modern rectangular silhouette — a format that delivers both architectural clarity and brilliant light return in colorless material.\u003c\/p\u003e\n\n\u003cdiv style=\"border: 2px solid #5b2c6f;
