2.73 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 2.73 carat cushion shape blue sapphire demonstrates how crystalline structure and considered cutting create a level of sparkle that is technically superior and visually striking. The gem is transparent and fashioned with a mixed brilliant cut that combines a brilliant faceted crown with angular pavilion facets, producing a complex network of light paths. Light entering the sapphire is repeatedly reflected within the gem before exiting through the crown, an effect intensified by corundum’s inherent optical properties and the precise facet junctions. The stone’s excellent polish minimizes surface scattering, allowing maximum internal reflection and crisp return of light to the viewer’s eye. The result is a lively, scintillating performance that shows flashes of intense blue and pinpoints of sparkle across the table and crown facets, a balance of brilliance and depth that mixed cutting aims to achieve.

Measured at 8.74 by 6.49 by 4.92 millimeters, this Ceylon, Sri Lanka origin sapphire has a vivid color intensity and a clarity grade of very slightly included when evaluated at eye level, attributes that together preserve strong light return and vivid saturation. The heat treatment enhancement has been applied to stabilize and intensify color in a manner consistent with established gemological practice, while the very slight inclusions contribute character without interrupting the gem’s optical performance. The cushion outline lends a classic silhouette that concentrates color at the center while the mixed brilliant faceting creates high contrast flashes and lively scintillation toward the edges. Offered by The Natural Sapphire Company, this sapphire illustrates how material properties, cut geometry, and surface finish combine to produce a gemstone whose sparkle is both dynamic and refined, suitable for settings that emphasize both color depth and faceted brilliance.
