1.23 Ct. Purple Spinel from Ceylon (Sri Lanka)

This transparent purple spinel weighs 1.23 carat and presents a classic cushion outline, with precise measurements of 6.71 x 5.85 x 3.91 mm. The cut is a mixed brilliant style, combining a brilliant facet arrangement on the crown with a faceted pavilion that is optimized to return light with controlled scintillation. The polish on all facets is excellent, producing crisp facet junctions and a clean pavilion that enhances the stone clarity. Clarity is graded as very slightly included when evaluated at eye level, with minute internal features that do not interfere with the visual field under normal wear, and which can be used strategically by a jeweler to orient the stone for maximum face up performance. The stone is unenhanced, natural, and originates from Ceylon, Sri Lanka, a provenance well regarded for spinel material, reported by The Natural Gemstone Company as part of its curated selection.

From a faceting perspective this cushion spinel demonstrates thoughtful proportioning. The recorded pavilion depth of 3.91 mm in relation to the average girdle span of 6.28 mm yields a depth proportion of 62.2 percent, a range that balances brilliance and saturation in colored stones. The mixed brilliant configuration permits broader table facets to present the purple body color distinctly, while smaller star and kite facets on the crown modulate dispersion and fiery flashes. Spinel is singly refractive, and unlike anisotropic gemstones this material does not exhibit pleochroic color shifts, which simplifies design decisions for stone orientation in multi stone layouts. The cutter achieved well aligned facet symmetry, which minimizes light leakage and preserves an intense color intensity that reads evenly across the crown without patchy zoning.

The cushion shape and the 6.71 x 5.85 mm dimensions make this 1.23 carat spinel particularly well suited for custom jewelry commissions. In a solitaire ring setting these proportions translate to a commanding face up size that remains comfortable for everyday wear, while the cushion outline lends itself to both classic four prong mounts and bezel settings that protect the girdle. For halo and cluster treatments the mixed brilliant crown integrates predictably with small pavé and round accents, because the primary facets orient light in a complementary manner to round brilliants. The moderate depth and substantial pavilion allow for secure bezel seat engineering, and the very slightly included clarity grade means inclusions will not complicate tight bezel carpentry or visible table placement. Designers seeking matched pairs for earrings can use the predictable single refractive behavior to mirror matched stones without concern for color shifting.

The origin, cut quality, and natural state of this spinel make it a superior candidate for bespoke pieces commissioned through The Natural Gemstone Company. Customers who prioritize material integrity will value the absence of heat or other enhancement treatments, as well as the excellent polish and well executed mixed brilliant faceting. For design consultations the stone can be supplied with facet orientation diagrams and high resolution imagery to assist CAD or hand sketch planning, and our team can advise on metal choices and setting profiles that preserve the intense purple saturation while providing long term protection. The hardness of spinel at about 8 on the Mohs scale, combined with its vitreous luster, ensures durability for rings, pendants, and bracelets, while the cushion silhouette offers an enduring visual language that complements both contemporary and period jewelry motifs. For technical buyers and bench jewellers seeking a reliable, naturally intense purple spinel from Ceylon, this 1.23 carat cushion shape gem is a precise and adaptable option from The Natural Gemstone Company.
