1.67 Ct. Blue Spinel from Ceylon (Sri Lanka)

This transparent 1.67 carat asscher octagon blue spinel from Ceylon presents precise proportions and refined craftsmanship, measuring 7.06 by 6.81 by 3.70 millimeters, with depth approximately fifty three percent, a dimension profile that preserves balanced light return in a step cut. The asscher faceting manifests as concentric rectangular steps on the crown and pavilion, producing a hall of mirrors effect that emphasizes clean flashes rather than dispersed brilliance, the large table and well defined girdle allowing the medium color intensity to read evenly across the face up. Clarity is graded very slightly included at eye level, inclusions are minimal and unobtrusive, and the excellent polish and tight facet junctions contribute to crisp facet reflections and optimal windowing control. No enhancement has been applied, ensuring that the color and transparency are entirely natural, and the octagonal symmetry was executed to minimize light leakage and maximize the characteristic step facet scintillation expected from a high quality asscher geometry.

When compared by hue and tone to blue gemstones from other famous localities, this Sri Lankan spinel displays a cool, slightly steel blue that differs from the more saturated, velvety cornflower blues associated with Kashmir sapphires, which tend to show deeper tone and richer saturation. Relative to classic Ceylon sapphires, which often exhibit a lighter, lively blue with a touch of violet, this spinel sits in a similar light to medium tonal range but with a cleaner, less velvety texture due to the step cut and inherent spinel refractive properties. Compared to Burmese and Vietnamese blue spinels, which can lean toward vivid pure blue or bluish purple with stronger saturation, this Ceylon example reads more muted and sophisticated, offering a cooler steel undertone rather than overtly vivid chroma. For design considerations, the medium intensity and asscher facets make this piece ideal for settings that emphasize geometric lines and color stability, the natural origin and absence of enhancement enhancing its appeal for collectors who prefer provenance and untreated material. The Natural Gemstone Company is pleased to offer this precisely cut, naturally colored Ceylon blue spinel as a gem that balances technical excellence with a distinctive, regionally influenced hue and tone.
