0.92 Ct. Greyish Blue Sapphire from Ceylon (Sri Lanka)

This 0.92 carat cushion shape sapphire presents an exacting combination of measured dimensions and considered cutting, 6.00 x 4.90 x 3.85 mm, that will appeal to connoisseurs who value proportion and optical performance. The stone is fashioned in a mixed brilliant cut, a deliberate faceting schema that marries a modified brilliant crown with a pavilion architecture optimized for light return. The crown facets are arranged to create controlled windowing through the table while preserving broad flash scintillation, and the pavilion exhibits a series of precise pavilion mains and lower girdle facets that reintroduce lost light as lively scintillation and pulse like reflections. The faint greyish blue color grade is evenly distributed across the cushion outline, and the shallow to medium depth allows the stone to read as a cool, airy blue under daylight and laboratory lighting. The excellent polish is evident on facet junctions and girdle finish, enabling crisp facet reflections and minimizing surface diffusion so the thin, pale tone of the sapphire remains clean and transparent rather than milky. The mixed brilliant approach was selected to maximize face up brightness in a stone of this size and tone, balancing retention of weight with optical efficiency.

Under magnification and at eye level the gem is graded as very slightly included, a clarity category that in this specimen translates to small, well isolated internal features that contribute to character rather than detract from visual appeal. The most distinctive inclusions are fine, silk like needles oriented along growth planes, appearing as delicate wisps that can concentrate into subtle web like structures in localized areas. Interspersed with these are sporadic pinpoint crystals that act as micro reflectors, yielding tiny pinpricks of mirrored light when the stone is tilted. In one quadrant there is a faint feather that is healed and comprised of translucent, fingerprint like morphology which disperses light rather than blocking it, creating a soft internal veil that accentuates the stone wide flash without compromising transparency. These inclusion types are typical of natural corundum from well formed geologic environments and they produce an unmistakable signature, a fingerprint for provenance and natural formation, that experienced buyers and gem cutters use to assess authenticity and cutting potential. The internal architecture interacts with the mixed brilliant faceting to create a layered optical effect, where the silk needles diffuse light into a silvery sheen while the pinpoints introduce discrete scintillation, resulting in a visual texture that reads as lively but refined.

This sapphire is unenhanced, no heat treatment or other artificial enhancement, a condition that preserves natural color distribution and inclusional character and which is increasingly sought by collectors who prioritize provenance and geological integrity. The stone is of Ceylon origin, Sri Lanka, a source known for producing sapphires with a lighter, more pastel to medium range of blue tones and characteristic internal silk. In design terms the pale greyish blue of this cushion sapphire provides an elegant counterpoint to warmer metal choices and to complementary gemstones. Consider pairing the sapphire with White Opal accent stones, specifically the White Opal type which offers a luminous, soft body tone and occasional play of color that will contrast gently with the sapphire coolness without overpowering it. A setting that employs low profile claws and a bezel edge to protect the shallow pavilion while allowing the mixed brilliant crown to breathe will preserve the eye level clarity and allow the silk inclusions to contribute their signature effect to the overall appearance. At The Natural Sapphire Company we focus on matching cutting strategy to material character, and this 0.92 carat cushion greyish blue sapphire exemplifies careful selection and cutting, unaltered natural color, and the kind of internal fingerprint that connoisseurs recognize and appreciate.
