1.10 Ct. Spinel from Ceylon (Sri Lanka)

This 1.10 carat cushion shape blue spinel from Ceylon is a study in precise cutting and material purity, presented by The Natural Gemstone Company. Measuring 6.71 by 5.35 by 3.45 millimeters, the stone exhibits an overall depth of approximately 57 percent, a proportion that balances face up presence with optimal light return. The cutter employed a mixed brilliant approach, combining a brilliant facet pattern on the crown with a carefully modified pavilion geometry, to maximize scintillation while preserving depth and saturation. Facet junctions are clean and crisply polished, and the excellent polish allows crisp specular highlights that enhance the gem s apparent brightness. As a spinel, the material is isotropic with a refractive index near 1.718, and a Mohs hardness of about 8, properties that contribute to durable, lively brilliance and uniform color distribution without pleochroic shift.

Optical and clarity attributes make this example particularly collectible. Clarity is graded as very very slightly included at eye level, effectively eye clean to unaided observation, with only minute internal features visible under magnification that do not detract from transparency or brilliance. Color is described as dark intensity with strong saturation, producing a velvety deep blue that reads as both stately and versatile under varied lighting. No enhancement has been applied, the stone is untreated, and origin is Ceylon Sri Lanka, a source renowned for fine spinel material and skilled lapidary tradition. The mixed brilliant cut, together with the dark, saturated color and the excellent polish, allows this spinel to act as a true centerpiece, whether set as a refined solitaire, framed in a halo for added contrast, or incorporated into a bespoke design that showcases depth and fire. For collectors and connoisseurs seeking a natural, well cut, durable blue spinel with documented provenance, this gem represents a compact but commanding statement piece, and The Natural Gemstone Company stands ready to provide additional imagery, facet maps, or setting recommendations to ensure the stone is shown to best advantage.
