2.55 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent oval blue sapphire weighs 2.55 carats, a weight that immediately signals premium quality for faceted Ceylon material, and its mass is expressed in a dimension set of 9.13 by 7.07 by 4.75 millimeters, yielding a length to width ratio of approximately 1.29, an elegant proportion for classic oval settings. The cutting style is faceted with a mixed brilliant cut, combining a brilliant faceted crown with a precisely modified pavilion geometry to optimize both scintillation and color delivery. The mixed brilliant arrangement concentrates smaller, well defined crown facets to produce lively facet contrast, while the pavilion design controls light leakage to reinforce the gem s vivid blue saturation, a balance achieved through precise facet junctions and consistent symmetry. The polish is excellent, and facet surfaces exhibit sharp edges and clean facet junctions, contributing to superior light return and enhancing the stone s apparent transparency and depth.

At a clarity grade of very slightly included, evaluated at eye level, the stone presents minimal inclusions that do not detract from overall visual performance, allowing the vivid color intensity to dominate the viewer s perception. The vivid color is intense and well saturated, characteristic of fine Sri Lankan sapphires that combine brightness with strong hue. This example has been heat treated, a stable and widely accepted enhancement that has been applied to improve color uniformity and clarity while preserving natural crystal structure, no additional treatments are present. A 2.55 carat sapphire with these technical attributes, originating from Ceylon, represents a scarce combination of weight, color intensity, and clarity, delivering an optimal balance for collectors and connoisseurs who value measurable gemological quality. The Natural Sapphire Company certifies the gem s provenance and treatment disclosure, and recommends settings that preserve pavilion light return and allow the crown facets to interact with ambient light, such as a low profile bezel or four prong head that respects the oval form, to showcase the stone s faceting sophistication, vivid hue, and the premium presence imparted by its 2.55 carat weight.
