0.89 Ct. Purple Sapphire from Ceylon (Sri Lanka)

This item is a transparent 0.89 carat pear shaped purple sapphire, precision cut to dimensions of 7.74 by 4.92 by 2.97 millimeters, presenting a length to width ratio of approximately 1.57. The stone is fashioned in a mixed brilliant cut, a choice that combines a brilliant style crown with a complementary pavilion geometry to optimize both fire and return of white light. Clarity is graded as very slightly included when evaluated at eye level, a level of inclusion that is visually minimal and that preserves strong light performance. Color is classified as medium intense purple, consistent across the table and crown, and the surface finish is rated excellent for polish, with facet junctions clean and sharp. The sapphire has been heat treated, a standard and stable enhancement for Sri Lankan material, and its documented origin is Ceylon Sri Lanka. This specimen is offered by The Natural Sapphire Company, with full details provided to support informed selection by a technically minded buyer.

The mixed brilliant cut is the defining technical attribute that enhances the sapphire's inherent optical properties, the crown is designed with a modified brilliant facet arrangement to create a broad, controlled table that maximizes dispersion without sacrificing overall brightness. The pavilion combines elongated facets that are cut to angles calibrated to corundum's refractive index, promoting internal reflection and directed light return toward the viewer. In a pear shape this interplay of crown and pavilion is critical, because the tapered lower point and the rounded upper shoulder distribute light differently across the stone. The cutter has balanced crown height and pavilion depth to maintain contrast and scintillation, the facet sizes are graded to avoid large dark areas or excessive leakage, and the mixed approach preserves strong pinpoint flashes as well as larger flashes of white light. Precision at the girdle and at the culet area ensures that facet intersections remain in phase through rotation, producing a uniform scintillation pattern that complements the medium intense body color. For a technical buyer, the result is a stone that demonstrates controlled brilliance, measured dispersion, and attractive optical symmetry.

Color and clarity interact with the cut to determine perceived saturation and brilliance, the medium intense purple benefits from the mixed brilliant geometry because the crown facets allow the hue to be viewed through a well defined table while the pavilion facets return controlled flashes that prevent the color from appearing washed out. Heat treatment has been applied to enhance and stabilize the purple zoning, and when executed correctly it improves color uniformity while maintaining the sapphire's natural crystal morphology. The very slightly included clarity grade indicates minor internal features that do not interrupt light transmission at typical viewing distances, and these inclusions can act as additional reflective planes under certain lighting angles, contributing nuanced character without degrading overall transparency. Craftsmanship is evident in the excellent polish, with smooth facet planes and clean facet junctions that reduce surface scattering and enhance both brilliance and luster. For setting considerations a precision bezel or custom head that respects the stone's proportions will maintain optimal light return, allowing the pear shape to display its engineered scintillation and color depth. The Natural Sapphire Company presents this Ceylon purple sapphire as a technically refined piece, suitable for connoisseurs seeking a gem with deliberate cutting strategy, documented treatment and origin, and an emphasis on optical performance.
