3.50 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 3.50 carat cushion shape blue sapphire measures 9.66 by 7.13 by 5.06 mm, and is cut in a mixed brilliant configuration that marries a faceted brilliant crown with precision pavilion faceting to optimize both color and scintillation. The mixed brilliant approach maintains a moderate table and well proportioned crown height to preserve the sapphire core color saturation, while the pavilion tableau is calibrated to reduce windowing and enhance return of light as pinpoint scintillation. Clarity is graded very slightly included as evaluated at eye level, which means inclusions are minimal and do not interrupt the gem s visual integrity, allowing the intense color intensity to remain dominant. The stone exhibits the classic pleochroic behavior of corundum with subtle shifts from deep blue to a cooler violet blue at oblique angles, a feature that highlights crystal orientation and natural origin. Polish is excellent, facet junctions are sharp, and overall symmetry reflects advanced lapidary control, the combination of cut and finish permitting clean facet reflections and a lively face up presence. Enhancement status is none, the stone is unheated, and origin is Ceylon Sri Lanka, a provenance known for producing sapphires with lively tone and saturated, yet bright blues.

In comparison to historical blue gems, this sapphire displays qualities that recall the attributes collectors admire in renowned Ceylon stones, where the Logan Sapphire is celebrated for its pure cornflower blue and the Stuart Sapphire for its regal depth, while the Star of India represents a different phenomenon with asterism. Our gem does not compete in scale with museum pieces, instead it offers an intersection of classical Ceylon saturation and modern cutting precision, delivering a heart of color and optical performance that is increasingly rare in unheated material. The unheated status gives it a geological authenticity that many historical sapphires possess, the intense color intensity combined with very slight inclusions yields a gem that reads as natural and alive, rather than chemically modified. The Natural Sapphire Company stands behind the materiality and origin of this sapphire, offering full documentation and bespoke mounting options that respect its proportions and light behavior, the mixed brilliant cut makes it especially well suited to settings that emphasize both table brilliance and pavilion derived fire, making it a technically compelling selection for buyers who value provenance, untreated color, and meticulous craftsmanship.
