0.26 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.26 carat round Ceylon blue sapphire from The Natural Sapphire Company presents precise cutting and a refined optical presence, dimensions 3.90 x 3.94 x 2.37 mm, mixed brilliant cut, clarity slightly included at eye level, medium color intensity, excellent polish, no enhancement. The mixed brilliant design on this stone combines a brilliant style crown with a pavilion faceting scheme that favors controlled step facets, a pairing that is especially effective for natural sapphires where preserving color and depth is paramount. The crown facets are proportioned to disperse incoming light into vivid scintillation across the table and star facets, while the step oriented pavilion facets act to deepen the face up blue by lengthening the internal light path and increasing selective absorption of longer wavelengths. This balance yields a stone that reads as lively in motion, with frequent bright returns, but also retains the characteristic Ceylon clarity and cool blue tone that collectors seek.

From a craftsmanship standpoint the cutter has prioritized symmetry and table sizing to optimize both light return and apparent size, a critical consideration at this small scale. The pavilion depth and crown angle are tuned to encourage total internal reflection rather than leakage through the girdle, so light entering the crown is redirected back through the table and crown facets, producing concentrated flashes and persistent brilliance. Excellent polish reduces microfacet diffusion, maintaining crisp facet junctions and sharp contrast between light and dark areas, which enhances face up contrast and perceived saturation. Slight inclusions evaluated at eye level do not detract from the optical performance, they are internal characteristics common to natural Sri Lankan sapphires and are often masked by the mixed faceting which redirects light around them. Offered untreated, and originating in Ceylon, this sapphire is well suited to a refined setting where its mixed brilliant cutting will maximize light play and color depth, a technical and aesthetic choice that reflects The Natural Sapphire Company attention to proportion and finish.
