1.25 Ct. Grey Spinel from Burma (Myanmar)

This Burmese grey spinel is a precise study in balanced cutting and material integrity, weighing 1.25 carat and measuring 6.96 by 5.40 by 3.86 millimeters, with a calculated depth of 62.4 percent relative to the mean of the length and width. The stone is fashioned in a traditional cushion outline, the softened corners and broad pavilion facets preserving weight while allowing an elegantly proportioned face up size. The cutter employed a mixed brilliant strategy, combining a brilliant style crown with a pavilion that integrates both brilliant and step facets to optimize internal reflection and controlled scintillation. Clarity is graded slightly included, evaluated at eye level, with minor internal features that do not compromise structural integrity or overall light performance. The surface finish is an excellent polish, indicating careful lapidary technique and tight facet junctions, and the stone is free of any enhancements or treatments.

Optical behavior of this spinel is governed by spinel crystallography and the cutter’s choices. Spinel is singly refractive, and this material displays the characteristic even light return and crisp windowing when proportions are well executed. The mixed brilliant design here produces a pleasing balance between broad flashes and small pinpoints of light, yielding lively scintillation in both diffuse and direct illumination. The color is an intense grey, the neutral baseline providing depth and presence while subtle cool blue violet undertones appear under certain light sources, enhancing perceived saturation without creating overt color zoning. The combination of intense color intensity and the precise pavilion depth amplifies contrast, which increases perceived brilliance despite the darker tone. The slightly included clarity grade contributes to the gem’s natural fingerprint, while aperture sighting reveals that inclusions are positioned and sized such that they do not interrupt the primary light paths nor affect durability for standard jewelry use.
