0.74 Ct. Purple Spinel from Ceylon (Sri Lanka)

This cushion shape purple spinel is a technically precise example of lapidary control and natural material quality, weighing 0.74 carat, and measuring 5.66 by 5.12 by 3.26 millimeters. The stone is fashioned in a mixed brilliant cut, with a brilliant style crown and carefully calibrated step facets on the pavilion, a combination chosen to balance strong scintillation with concentrated color saturation. Transparency is high, described as transparent, and the clarity has been assessed as very slightly included at eye level, indicating only minor internal features that do not materially interrupt light transmission. Color is a true medium intensity purple with a faint cool undertone typical of Ceylon spinel, and the polish is excellent, yielding crisp facet junctions and clean reflections. This spinel is natural and untreated, with no enhancement, and its origin is documented as Ceylon Sri Lanka, adding a provenance that collectors recognize as historically significant for spinel quality. Typical physical parameters for spinel inform the cutter with a refractive index approximately 1.718, a specific gravity in the region of 3.60 to 3.62, and a low dispersion near 0.018, and these optical constants are reflected in the gemology of this piece.

From a cutting and proportion perspective the gem exhibits a depth that measures approximately 60 percent relative to the average of its length and width, a depth choice that optimizes internal color concentration without inducing excessive windowing. The mixed brilliant form here employs a restrained table facet, and a series of precisely angled crown facets that manage the entry and return of light to produce both broad flashes and fine scintillation. The step pavilion has been executed to reinforce the medium color intensity, creating layered zones of color when viewed through the table, while the brilliant crown preserves lively dispersion and sparkle. Facet symmetry and alignment are observable in the even patterning seen in face up images, and the excellent polish enhances apparent luster and minimizes surface abrasion that could scatter light. For a gem of these dimensions and weight, the cutter has prioritized optical balance, producing a stone that reads larger on the finger than its carat weight might suggest, due to efficient light return and proportional outline.

Ethical sourcing and traceability are integral to the appeal of this spinel for the conscious collector, and The Natural Gemstone Company places provenance as a central attribute when presenting natural stones. This spinel originates from Ceylon Sri Lanka, where many high quality spinel deposits are worked by small scale and artisanal operations, and our sourcing protocols emphasize direct purchasing, fair compensation to miners, and documentation of chain of custody from mine to market. The absence of heat treatment or other enhancement preserves both the intrinsic value and the natural story of the stone, enabling collectors to acquire a gem that is unaltered from its formation. Environmentally responsible practices are encouraged at collection sites through partnerships and support of local initiatives that mitigate landscape impact, and our internal audit process evaluates labor conditions and supports traceable supply lines, providing assurance to buyers who prioritize ethical procurement.

This cushion purple spinel is well suited for a conscious jewelry collection that values technical excellence and verifiable origin, and it adapts to a variety of settings and design approaches. For maximum brilliance and the most lively face up appearance, a four prong or six prong mounting in white metal will emphasize the gem s scintillation, while a low bezel setting in warm metal will deepen the perceived saturation and create a more intimate tone on the finger. Its 0.74 carat weight and compact dimensions make it an elegant solitaire for a delicate ring, a refined center for a halo composition, or a distinctive element in bespoke earrings or a pendant. Because the stone is unenhanced and precisely cut, it retains collector value and long term stability, and documentation of origin from Ceylon Sri Lanka is available on request. Clients who wish to examine additional images, request exact facet diagrams, or obtain a formal gemological report are invited to contact The Natural Gemstone Company, and our team will provide condition verified photographs and provenance details to support informed acquisition.
