GIA Certified 5.75ct Unheated Ceylon Sapphire | Master Concave Cut | Rare Octagonal Lilac

Acquire a true "one-of-one" with this monumental 5.75-carat natural sapphire. While its Sri Lankan origin and unheated status place it in the top 1% of all gemstones, it is the master-level Concave Modified Brilliant Cut that elevates this piece into the realm of wearable art.
Unlike flat-faceted stones, the concave-curved facets act as internal lenses, gathering light to create an "electric" internal glow and 3D depth that is virtually impossible to find in a sapphire of this size.
