2.37 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 2.37 carat oval blue sapphire measures 9.73 by 7.53 by 3.67 millimeters, yielding an approximate depth ratio of 42.5 percent, and is presented in a mixed brilliant cut that balances scintillation and color saturation. The mixed brilliant faceting combines a brilliant facet arrangement with modified pavilion facets, producing lively crown facet play while maintaining strong face up color, and the excellent polish enhances facet crispness and light return. Clarity is graded as very slightly included when examined at eye level, with inclusions that do not compromise transparency or the gem's visual appeal. Color intensity is described as dark, offering a deep, velvety blue that reads consistently across the table and crown facets, a characteristic often prized in formal and heritage jewelry. The sapphire has been heat treated, a stable and well established enhancement used to improve color uniformity and clarity, and its documented origin is Ceylon, Sri Lanka, a source long recognized for high quality blue sapphire material.

In heritage and craftsmanship terms this stone aligns with centuries of Ceylon sapphire use in regal and ceremonial jewels, where deep blue sapphires were mounted as symbols of authority, protection, and devotion, and were commonly set in crowns, rings, and religious ornamentation. For contemporary settings the shallow to medium depth suggests a design that emphasizes face up presence, for example classic four prong or bezel settings that preserve the stone profile while protecting the girdle, and open backed settings will maximize light passage when a brighter face up appearance is desired. The combination of a mixed brilliant cut, very slightly included clarity at eye level, excellent polish, and heat treatment applied to Ceylon material gives this sapphire both traditional provenance and technical refinement. This example is offered and described by The Natural Sapphire Company, and it is well suited for an heirloom ring or pendant that references historical sapphire usage while benefiting from modern cutting and finishing techniques.
