0.86 Ct. Purple Spinel from Ceylon (Sri Lanka)

This 0.86 carat oval purple spinel from Ceylon Sri Lanka is precisely measured at 6.40 x 5.14 x 3.54 millimeters, with an overall depth of approximately sixty one percent, a proportion deliberately chosen to optimize light return in an elongated outline. The cutting style is faceted, executed as a mixed brilliant cut with a brilliant style crown coupled to a modified pavilion, producing a controlled balance between table brilliance and pavilion return. The cutter retained a slightly rounded girdle to preserve weight and reduce chipping risk, while the excellent polish removes facet traces and enhances specular reflection. Clarity is graded as slightly included at eye level, with minor pinpoint and crystal inclusions that are well distributed and do not interrupt the optical flow across the table. Color intensity reads as light purple with even saturation across the face up, and the stone is natural without any enhancement, an important factor for collectors and connoisseurs, represented by The Natural Gemstone Company.

Under daylight and high color temperature light sources, such as natural midday sun and cool white LEDs, the mixed brilliant geometry projects vibrant table brilliance and small scintillation flashes from the crown facets, showing the light purple hue distinctly and evenly. Under warm incandescent or candlelight, the stone exhibits a softer tone, the light purple leaning subtly toward warmer violet, while the excellent polish allows lively pinpoint scintillation and strong contrast between facet planes. Under focused spot lighting the pavilion construction reveals deep flashes and a concentrated return that enhances perceived saturation, while diffuse fluorescent illumination accentuates overall body color without strong pinpoint flashes. Spinel is singly refractive with negligible pleochroism, so color remains consistent when viewed from different angles, and the hardness at approximately Mohs eight gives good resistance to wear and polishing stability. The mixed brilliant cut and proportions minimize the typical bowtie effect found in elongated ovals, producing an even visual field and predictable light behavior in ring, pendant, or stud settings. For clients seeking a natural, well cut Ceylon spinel with reliable performance across lighting conditions, this example from The Natural Gemstone Company combines technical precision in cutting, truthful natural color, and durable material qualities, making it suitable for both collectors and fine jewelry applications.
