2.55 Ct. Purplish Blue Sapphire from Ceylon (Sri Lanka)

This 2.55 carat cushion shape purplish blue sapphire measures 9.17 by 6.27 by 4.17 millimeters, and combines classical form with precision cutting to deliver both presence and technical excellence. The gem is transparent, untreated, and of Ceylon origin, with an intense color intensity and an excellent polish. Cut as a faceted stone in a mixed brilliant cut, the cutter employed a brilliant crown with a modified step pavilion, allocating facet junctions and crown angles to enhance return of medium and long wave blue tones while preserving the stone color at varied viewing angles. Proportions are carefully balanced to maintain a generous table that anchors face up color, while smaller crown facets generate acute scintillation. The very very slightly included clarity grade evaluated at eye level confirms exceptional visual purity, and the lack of thermal or clarity enhancement ensures the internal character is wholly natural.

The stone carries a signature of inclusions that is diagnostic of fine Sri Lankan material, described here in technical detail for the discerning buyer. Under 10x magnification the sapphire reveals fine oriented needle silk aligned along growth zoning, occasional isolated crystal inclusions with subtle negative crystal outlines, and healed fingerprint type planar features that trace early growth interruptions. These features are minute and well separated from key facet junctions, so they do not disturb the macroscopic transparency, instead they contribute to a delicate internal texture that softens high contrast flashes and produces a slightly velvety depth to the blue, a quality prized in Ceylon sapphires. The distribution and morphology of these inclusions guided the cutter when setting pavilion angles and facet proportions, the objective being to place any minor features away from the table plane and to exploit internal reflections for a lively scintillation pattern. For collectors and gemological professionals these inclusion types, together with the unheated state and the stone's pleochroic response, provide reliable provenance indicators consistent with Sri Lankan geology. The Natural Sapphire Company can provide detailed photographic magnification, inclusion mapping, and independent laboratory documentation on request, enabling confident assessment of this sapphire both as a precision cut gem and as a collectible natural specimen.
