0.81 Ct. Violet Sapphire from Ceylon (Sri Lanka)

This 0.81 carat transparent cushion violet sapphire from Ceylon offered by The Natural Sapphire Company is a study in calibrated faceting and natural color. The gem measures 5.74 by 5.11 by 3.27 millimeters, producing a depth percentage of approximately 60 percent, a proportion that supports a balanced face-up appearance and optimal light return for a cushion outline. The cutter employed a mixed brilliant cut, combining a brilliant-style crown with a pavilion that preserves color saturation while delivering scintillation. The crown facets are arranged to produce lively dispersion and pinpoint scintillation across the table and crown facets, while the modified pavilion facets direct light back through the stone in broader flashes, enhancing perceived size and depth of color. Excellent polish across all facet junctions minimizes light scattering and maximizes contrast between bright flashes and the rich violet body color, yielding a crisp, tactile finish visible at all viewing distances.

From a clarity and treatment perspective this sapphire is particularly notable. It is transparent and graded as very, very slightly included at eye level, meaning the stone presents with exemplary optical cleanliness when viewed without magnification. Microscopic inspection typically reveals only minor pinpoint or rutile silk that does not interrupt the face-up brilliance or weaken the structural integrity. The stone is unenhanced, with no heat or diffusion treatments, an attribute that appreciably increases rarity and collector value for a specimen of this intensity. Origin from Sri Lanka, historically referred to as Ceylon, contributes to the gemological profile, as Ceylon material often exhibits a lively, saturated tone and a delicate interplay of blue and purple which this piece displays consistently across different lighting environments.

When compared to more common gemstones the optical behavior of this violet sapphire merits close attention. Diamonds, with their high refractive index and strong dispersion, produce exceptional white light return and a signature fire. Corundum’s refractive index is lower, so the diamond-style fire is not matched, yet this sapphire achieves an alternative and compelling brilliance through color-saturated light return and controlled scintillation. The mixed brilliant cut enhances the apparent brightness by concentrating reflections into sharper, color-bearing flashes, rather than relying on spectral dispersion alone. Compared with rubies and standard blue sapphires, which tend to absorb more in the red or blue regions respectively, a violet sapphire occupies a spectral niche where both blue and red components are present but balanced, allowing the internal reflections to read as vivid violet instead of being masked by a dominant hue. Against tanzanite and other pleochroic gems, sapphire’s superior hardness, resistance to wear, and stable, untreated color make it a more durable choice for everyday jewelry while still offering dynamic color shifts under angular viewing.

For the technically minded buyer, the combination of proportions, cut style, color intensity, and lack of enhancement defines why this stone stands out. The cushion outline paired with a mixed brilliant scheme maximizes face-up spread for the given carat weight, so the 5.74 by 5.11 millimeter table reads slightly larger on the finger than a deeper round of equal weight. The intense color grade provides strong absorption peaks that heighten contrast between bright facet flashes and the saturated body tone, producing a sense of depth often described as velvety, yet the excellent polish ensures those flashes remain crisp rather than diffuse. As a natural, untreated Ceylon sapphire with very, very slight inclusions at eye level, this gem is ideal for connoisseurs seeking a balance of technical precision and authentic origin. The Natural Sapphire Company is pleased to present this stone as an example of skilled cutting and rare coloration, suitable for a refined engagement center or a bespoke piece where both optical performance and provenance are paramount.
