0.99 Ct. Spinel from Ceylon (Sri Lanka)

This transparent 0.99 carat oval spinel presents a refined combination of size, color, and clarity, originating from Ceylon Sri Lanka, and supplied through The Natural Gemstone Company. The gem measures 6.44 x 5.59 x 3.97 mm, a proportion that suits a wide range of mounting styles while maintaining optical balance. The body color is a restrained pinkish purple with medium color intensity, a tone that reads as distinctly colored yet retains notable transparency and light transmission. Clarity is graded as slightly included at eye level, a designation that indicates minor internal features visible under careful inspection but not materially detrimental to overall transparency or to the gem's visual appeal. The spinel is unenhanced, its natural color and crystal integrity preserved, and it has been finished to an excellent polish that contributes to its surface luster and the clarity of facet reflections.

The cutting style is a mixed brilliant, and the geometric faceting has been executed to promote maximum light play, a key attribute for gems intended to deliver lively optical performance. The mixed brilliant approach combines a faceted crown with a pavilion geometry that encourages both internal reflection and controlled light return. The crown facets capture incoming light and disperse it into the pavilion, while the pavilion facets and their angular relationships return much of that light back through the crown, enhancing brilliance. Facet junctions and symmetry are well calibrated, producing crisp facet junctions and consistent facet patterning, characteristics that reduce unwanted light leakage. The oval outline is balanced between length and width, a proportion that minimizes pronounced bow tie effects while preserving the oval s ability to distribute scintillation across the length of the stone. The table and crown heights are proportioned to allow for a broad face up display, while the pavilion depth has been tuned to support contrast patterning, so that flashes of brightness alternate with darker facet windows, creating dynamic play as the stone or the observer moves. The excellent polish further enhances facet clarity, reducing surface diffusion and allowing sharp flashes of light to emanate from both the crown and pavilion facets.

From a practical perspective the dimensions and weight make this spinel a versatile choice for both classic and contemporary settings, suitable for a solitaire mount or for inclusion as the central stone in a more complex design. The medium intensity pinkish purple responds well to varied lighting environments, presenting a cooler purple cast in LED or north light, and a warmer pinker overtone in incandescent or warm daylight, a characteristic effect of naturally colored spinel from Ceylon. The slightly included clarity means that inclusions are small and do not materially compromise durability, spinel being a durable gem species with good resistance to daily wear. The origin, unenhanced status, and precise cutting details have been documented by The Natural Gemstone Company, providing provenance and treatment transparency for connoisseurs and designers. For those specifying stones for custom work, the measured proportions 6.44 x 5.59 x 3.97 mm and the mixed brilliant faceting offer reliable parameters for setting templates and for anticipating the stone s face up presentation, while the excellent polish and calibrated facet geometry ensure predictable optical performance once set.
