1.52 Ct. Greenish Blue Spinel from Ceylon (Sri Lanka)

This transparent greenish blue spinel weighs 1.52 carats and measures 6.17 by 6.03 by 5.40 millimeters, presented in a faceted, asscher octagonal form. The gem displays a dark color intensity that gives the tone depth and presence, while its clarity grade is eye clean as assessed at eye level, offering an unobstructed view into the stone. The cut is executed with precision and an excellent polish, and there has been no enhancement, with origin traced to Ceylon Sri Lanka. The combination of weight, dimensions, and finish yields a compact yet impactful gem, suitable for settings that showcase its square octagonal geometry and deep, even color. The Natural Gemstone Company confirms the natural, untreated provenance and the careful cutting and finishing that preserve the inherent character of this spinel.

The asscher cut enhances the spinel core optical properties by organizing light with geometric clarity rather than diffuse sparkle, the stepped pavilion and concentric square facets channel incoming light into layered internal reflections that emphasize depth and color saturation. The broad table and proportional crown allow the viewer to see large, clean flashes of color across the pavilion planes, while the step facets produce a balanced interplay of light and shadow that highlights the stone clarity and faceting symmetry. Excellent polish minimizes light scattering at facet junctions, improving return of light to the eye and maintaining crisp facet outlines, the relatively deep pavilion contributes to the rich dark intensity by increasing internal light travel and selective absorption. Together these attributes produce a composed optical effect that reads as depth and richness rather than excessive brilliance, making the stone particularly well suited to designs that favor architectural lines and refined presence. For clients and designers seeking a natural, well cut greenish blue spinel from Sri Lanka, this piece represents a clear example of how disciplined cutting elevates the gem by maximizing light control, color expression, and visual depth.
