Untreated Ceylon sapphires in this size and with this color purity are exceptionally rare and increasingly difficult to source. The square mixed cut delivers strong brilliance, crisp light return, and excellent luster, giving the stone a powerful face-up presence. The blue hue is clean and elegant, with a refined saturation typical of the finest Sri Lankan material. This is not a commercial sapphire. It is a collector-grade gemstone, sought after for its origin, untreated status, and double certification—a true rarity to own in a serious collection.
