2.18 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 2.18 carat radiant shape blue sapphire from Ceylon, Sri Lanka, presents precise dimensions of 6.94 by 6.91 by 4.91 millimeters, reflecting careful weight retention and proportional planning by the cutter, The Natural Sapphire Company. The gem is described as very slightly included, evaluated at eye level, which yields excellent apparent clarity when viewed face up, and the medium color intensity offers a clear, lively blue that is true to classic Ceylon material. The stone has a radiant cut with excellent polish, and it is untreated, no enhancement, which preserves the natural crystal habit and original color saturation. These objective specifications combine to produce a sapphire that balances durable wearability with a refined visual presence suitable for a fine custom mount.

Technically, the radiant cut used on this sapphire is a hybrid faceting schema that marries a brilliant style crown with a denser pavilion faceting arrangement, producing a multifaceted light engine that multiplies internal reflections and scintillation. The table to overall dimension relationship and the measured depth of approximately 71 percent work together to retain color while optimizing light return, allowing white light to refract and reflect within the pavilion before exiting through the crown facets as flashes of blue and lively white scintillation. Excellent symmetry and polish minimize light leakage at facet junctions, sharpening facet contrast and enhancing dispersion without sacrificing the evenness of the medium color intensity. The very slightly included clarity grade means that inclusions are minor and do not impede the passage of light or the gem s transparency, so the radiant faceting pattern reads cleanly when set. For design considerations, the cushionlike outline and cropped corners of the radiant silhouette concentrate color toward the table face up, producing a bright, substantial presence on the finger while the facet geometry maintains strong brilliance and a lively pattern of scintillation when viewed in motion. This sapphire exemplifies how precise cutting, careful proportioning, and superior polish can amplify a natural stone s optical properties, offered by The Natural Sapphire Company as a premium untreated Ceylon sapphire.
