0.90 Ct. Greenish Blue Spinel from Ceylon (Sri Lanka)

This 0.90 carat cushion shape spinel measures 5.88 x 5.29 x 3.76 mm, and presents as a transparent greenish blue specimen cut in a faceted mixed brilliant configuration, combining a modified step crown with a brilliant pavilion to balance color saturation and light return. The mixed brilliant architecture emphasizes a broad table and softened crown facets to capture and hold the dark color intensity, while the pavilion geometry is calibrated to optimize internal reflection and scintillation for a gem of this size. Clarity is graded as very very slightly included, evaluated at eye level, and the excellent polish and precise facet junctions minimize the visual impact of minute inclusions, preserving clean face up appearance. No enhancement has been performed, so the optical properties and natural tone are entirely native to the crystal, and the untreated state is an important technical attribute for connoisseurs and for subsequent gemological verification.

Provenance from Ceylon Sri Lanka adds measurable value to this spinel, because Sri Lankan deposits are historically and commercially renowned for producing spinels with stable, saturated hues and crystalline clarity, attributes that are desirable in high quality faceting material. The island has a long established lapidary tradition and experienced cutters who understand the material response of Ceylon spinel, enabling the execution of mixed brilliant proportions that retain depth of color without sacrificing brilliance. From a market perspective, documented Ceylon origin enhances provenance, supporting premium positioning for collectors and creators seeking natural, untreated material with reputable sourcing. At The Natural Gemstone Company we emphasize these technical and provenance characteristics, recommending this 0.90 carat cushion spinel for fine jewelry center settings where the dark color intensity can be showcased, or as a specialist collector piece where untreated Ceylon origin and meticulous faceting translate into enduring aesthetic and investment value.
