1.18 Ct. Pinkish Purple Spinel from Ceylon (Sri Lanka)

This transparent 1.18 carat cushion shape spinel measures 6.30 x 5.48 x 3.96 mm and presents an intense pinkish purple hue that reads uniformly across the table, the girdle and the pavilion. The cutter selected a mixed brilliant configuration, pairing a brilliant crown with a modified step pavilion to yield strong contrast scintillation and broad light return, and the overall proportions produce a depth of approximately 67.2 percent which contributes to the stone's vivid color saturation and perceived size. Clarity is graded as very slightly included at eye level, with only minute pinpoint inclusions visible under close inspection, inclusions that do not materially interrupt face up brilliance. The polish is excellent, facet junctions are crisp and well executed, and there has been no enhancement, leaving this gem in its natural state from Ceylon, Sri Lanka. The Natural Gemstone Company presents this spinel as a ready centerpiece for bespoke jewelry or a discerning collection.

From an optical and material perspective this spinel demonstrates the qualities advanced buyers seek. The mixed brilliant faceting maximizes internal reflection while the modified step pavilion deepens color without sacrificing return of white light, producing lively flashes and even dispersion. Spinel is an isotropic gem with a typical refractive index range near 1.712 to 1.718 and low dispersion near 0.018, properties that this cut takes advantage of to show a saturated pinkish purple rather than strong color zoning or pleochroism. Hardness is approximately eight on the Mohs scale, ensuring durability for daily wear when securely set. The precise dimensions and well balanced pavilion to crown relationship indicate careful preforming and finishing by an experienced cutter, with attention to weight retention and optimal color presentation. For collectors and jewelers seeking a singular focal stone, this 1.18 carat Ceylon spinel offers intense color, refined cutting, and superior polish, making it an exceptional choice as a ring center, pendant focal point, or museum quality addition to a curated gemstone cabinet.
