1.30 Ct. Greyish Violet Spinel from Ceylon (Sri Lanka)

This is a transparent 1.30 carat cushion shaped greyish violet spinel, with precise dimensions of 6.81 x 5.69 x 4.04 mm, offered by The Natural Gemstone Company. The stone is faceted in a mixed brilliant cut which combines the scintillation of brilliant faceting with the color presentation of step elements. Clarity has been evaluated at eye level as slightly included, a common and acceptable grade for natural spinel which indicates that minor inclusions are present but do not dominate the appearance when viewed without magnification. Color intensity is described as medium, producing a sophisticated greyish violet tone that reads differently under varied lighting, and the polish is excellent which enhances surface smoothness and overall brilliance. Importantly, this spinel is natural with no enhancement, a critical attribute for buyers who prioritize untreated gemstones, and its origin is Ceylon Sri Lanka, a classical and respected source for fine spinel that has produced many historically significant gems.

The mixed brilliant faceting and carefully chosen cushion geometry work together to maximize light performance, producing a lively interplay of brilliance and fire. In this cutting style, the cutter has balanced pavilion and crown facet arrangements to optimize return of incident light while preserving color depth, and the geometric precision of each facet junction contributes directly to scintillation and patterning. The cushion outline softens the overall presentation, allowing larger facet planes to act as windows for internal reflection, yet the mixed brilliant layout maintains plentiful small facets that break light into discrete flashes. Because spinel is isotropic with a refractive index near 1.718, it does not show double refraction, so the light behavior you observe is governed by facet angles and polish quality, rather than optical anisotropy. The excellent polish on this piece ensures minimal light leakage at the surface, and the measured proportions support efficient light return, which together create maximum perceived brightness for the medium color intensity of the stone.

For the educated buyer this 1.30 carat Ceylon spinel represents a blend of natural provenance, durable material properties, and gemological integrity that warrants attention. Spinel is a robust gem for daily wear with a Mohs hardness of 8 and a specific gravity in the mid 3s, making it suitable for a variety of settings, while the absence of enhancement preserves both rarity and long term value relative to treated alternatives. The slight inclusions described at eye level are consistent with natural formation and often confirm authenticity for buyers who are familiar with gemological trade practice, while the medium greyish violet hue is increasingly sought after for its subtlety and versatility, allowing it to pair elegantly with both warm and cool metal choices. At The Natural Gemstone Company we emphasize transparent information and accurate grading, and we can provide high resolution images and discussion of setting options that will complement the cushion profile and mixed brilliant faceting, or arrange third party laboratory documentation when desired. If you are considering this spinel for personal wear or as a considered investment, the combination of natural origin, no enhancement, excellent polish, and a cut designed to maximize light play makes this piece a sound and appealing choice.
