1.16 Ct. Cobalt Spinel from Ceylon (Sri Lanka)

This transparent Ceylon cobalt spinel weighs 1.16 carat, and presents in a classical oval outline with precise dimensions of 7.66 by 5.65 by 3.80 millimeters, cut to a mixed brilliant schema. The cutter has combined a brilliant faceted crown with a modified pavilion architecture, producing a controlled balance between scintillation and deep color saturation. The pavilion depth yields a full body and creates a face up appearance rich in intense blue, the depth measuring approximately 57 percent relative to the average diameter, which optimizes light return while maintaining strong color presence. Facet junctions are sharply executed, table and bezel facets align to promote even sparkle across the oval surface, and the excellent polish amplifies the gem s internal reflections and surface luster. Clarity is graded as very very slightly included at eye level, effectively eye clean, with only minute natural features detectable under magnification, which preserve the gem s transparency and contribute to crisp facet contrast. This specimen is unenhanced, its cobalt derived color is natural, and its Sri Lankan origin imparts the classic Ceylon blue character sought by connoisseurs.

For engagement use this cobalt spinel represents a technically superior and emotionally distinct alternative to traditional stones, combining robust wearability with exceptional optical performance. Spinel s durability on the Mohs scale supports everyday wear, and the intense, evenly distributed blue offers the visual weight of a larger caratage when set face up in typical ring proportions. The oval geometry at 7.66 by 5.65 millimeters sits comfortably on a range of finger sizes, and the mixed brilliant cut adapts well to both low profile bezel settings that emphasize clean silhouettes, and open prong or halo designs that maximize brilliance and perceived size. As supplied by The Natural Gemstone Company this cobalt spinel arrives with full disclosure of origin and enhancement status, allowing confident selection for a lifetime piece. For buyers who prioritize natural color, precise cutting, and enduring structure, this stone is an ideal engagement choice, marrying scientific craftsmanship with the timeless appeal of Ceylon blue.
