1.94 Ct. Spinel from Ceylon (Sri Lanka)

This 1.94 carat oval purplish pink spinel measures 8.66 by 6.81 by 4.34 millimeters, and presents a classical mixed brilliant faceting scheme combined with proportions that favor both color saturation and optical performance. The length to width ratio is 1.27, providing an elegant oval outline that reads larger face up than its carat weight might suggest. The depth is 4.34 millimeters which represents approximately fifty point one percent of the length, a proportion that indicates a thoughtful balance between pavilion depth and crown height. The clarity has been evaluated at eye level as very very slightly included, translating to an eye clean appearance under normal viewing conditions. The color intensity is intense, the polish is excellent, there are no enhancements, and the stated origin is Ceylon Sri Lanka. The Natural Gemstone Company documents and certifies these attributes, and offers this spinel as a natural untreated example of the material from a classic locality.

The mixed brilliant cut deployed in this stone marries the energetic light return typical of round brilliant facet arrangements with selective step facets that help concentrate and showcase color. On the crown a compact table bordered by star and kite facets disperses incident light into a lively range of flashes while preserving uniformity of tone across the face of the gem. The pavilion carries a combination of pavilion mains and modified step facets that act to channel light back through the crown in controlled pulses, producing contrast that defines both scintillation and face up brilliance. The engineered interplay between the crown angle and pavilion angle in this configuration minimizes direct leakage of light through the girdle or pavilion, and simultaneously avoids over flashing that would dilute the perceived color. For spinel a mixed scheme is especially effective because the material exhibits a modest dispersion value and a refractive index near one point seven one eight, so maximizing broad patch brightness and contrast is the most reliable way to enhance perceived fire and life.

Color performance in this purplish pink spinel is a direct outcome of hue and saturation interacting with cut geometry. The intense color intensity reported here benefits from the slightly deeper pavilion and a proportionate table that limit the amount of white light returned as a single flat plane, while promoting multiple internal reflections that layer color without causing muddiness. Spinel is isotropic and lacks the strong pleochroism seen in some other gem species, so the hue reads consistently as purplish pink across viewing angles. Because spinel dispersion is relatively low the cutter must optimize facet angles and sizes to favor vivid face up color over excessive spectral breakup. The excellent polish on this specimen reduces surface scattering and enhances the clarity of internal reflections, allowing the saturated purplish pink to project with both intensity and purity. The absence of any heat treatment or other enhancement means the gem’s intrinsic chromophores are naturally presented, and the origin from Ceylon Sri Lanka contributes to a known geological context for the color palette often associated with that locality.

Clarity and finish details further underline how the cut enhances optical performance. The very very slightly included clarity grade evaluated at eye level indicates inclusions that are minimal in size and limited in number, and that do not interrupt the primary light pathways through the crown and pavilion. When inclusions are small and positioned away from the central table, the mixed brilliant arrangement disperses and conceals them via scintillation and dancing light, preserving a visually clean window to the gem’s color. The excellent polish and careful facet junctions ensure minimal light diffusion at the surface, which in turn increases contrast between bright and dark facet zones and sharpens the perception of depth. Taken together the proportions, facet design, and finish result in an oval spinel that reads as lively and deeply colored under both direct and diffuse lighting conditions, and that responds predictably across illumination environments. The Natural Gemstone Company stands behind the measured proportions and natural untreated status of this spinel, and recommends it for connoisseurs seeking a technically well executed example of Ceylon purplish pink spinel suitable for high jewelry applications.
