0.95 Ct. Greyish Blue Spinel from Ceylon (Sri Lanka)

This listing presents a transparent 0.95 carat radiant shape spinel, measuring 6.49 x 5.13 x 2.96 mm, sourced from Ceylon Sri Lanka, offered by The Natural Gemstone Company. The cutting style is faceted, executed in the radiant mixed cut that marries trimmed corners with an array of brilliant and step facets to maximize scintillation and preserve a strong face up presence. Color is a greyish blue with medium color intensity, producing a sophisticated cool tone that sits between steel blue and pale navy depending on ambient light. Clarity is graded slightly included when evaluated at eye level, with small internal features that do not compromise structural integrity, and polish is evaluated as excellent, yielding crisp facet junctions and clean light return. There has been no enhancement to this spinel, preserving natural color and inclusion characteristics, and standard gemological properties for spinel apply, with a refractive index near 1.718, dispersion that yields subtle fire, and a Mohs hardness of about 8, providing durable wearability for most jewelry uses.

The radiant cut of this 0.95 carat spinel emphasizes both brilliance and a broad face up appearance, the table facet presenting a clear window into the pavilion where a controlled mix of step and brilliant facets choreographs light return. The rectangular proportions and trimmed corners create a geometric framework that fits well in modern and classic settings, while the pavilion depth and girdle profile are engineered to balance light leakage with surface spread. The slight inclusions are positioned and sized such that they may be effectively masked by prong tips or a bezel seat, or alternatively turned into a design feature through an open gallery that allows light to traverse the stone and animate the internal characteristics. The excellent polish and facet symmetry enhance light performance, producing crisp flashes under point light and a steady body color under diffuse light. Because the stone is untreated, its medium color intensity and internal features provide a natural aesthetic prized by connoisseurs who favor authenticity over uniformity.

Customization options are extensive, this spinel being particularly versatile due to its radiant geometry and compact dimensions. For a classic statement, a four prong or six prong solitaire head will showcase the rectangular table while allowing maximum light entry, prongs set to kiss the girdle at the trimmed corners to protect the stone from lateral impacts. A full bezel offers a low profile, protective solution ideal for active wear, the bezel wall milled to follow the stone outline for a seamless profile. For added brilliance, a halo of micro pavé diamonds or white sapphires can be designed to visually enlarge the face up area, with careful pavilion clearance to avoid girdle stress. East west orientation implants contemporary energy and reduces perceived length for certain finger shapes, while three stone settings bring flank stones that balance color and weight, using tapered baguettes or trillion accents to maintain architectural coherence. Tension settings are technically feasible due to spinel toughness, however precision milling, finite engineering of contact surfaces, and internal stress analysis are recommended to ensure secure retention, and these should be executed by jewelers experienced in tension mountings. Cluster and cocktail settings can exploit the greyish blue hue against warm metal backdrops for high impact.

Material pairing, fabrication techniques, and jeweler instructions are provided to guide a bespoke creation around this gem. Platinum or 18 karat white gold will emphasize cool steel undertones and create a modern, high contrast presentation, while 18 karat yellow gold and 18 karat rose gold will warm the palette and shift the perceived hue towards slate blue or silvery lavender, respectively. For settings with accent stones, select diamonds with a color grade that complements the greyish blue body tone, or choose mint to off white sapphires for a softer contrast. Micro pavé work around a halo or shank should be executed with bead setting and burnishing to avoid thermal stress, and prongs should be formed with knife edge tips then work hardened and retipped for durability. Bezel seats must be milled with an internal contour that matches the girdle profile, with the seat depth aligning to the pavilion depth of 2.96 mm plus a small clearance to prevent pressure on facet junctions. For flush and channel settings, precise stone measurement and a friction fit tolerance of a few hundredths of a millimeter is advisable, fabrication to be completed with fine polishing and ultrasonic cleaning only after setting to maintain surface quality.

For customers and designers interested in bespoke work, The Natural Gemstone Company can provide additional imagery taken under controlled lighting, and we advise that the gemstone be supplied to the bench jeweler for final fit verification prior to permanent setting. The natural, unenhanced origin from Ceylon Sri Lanka makes this spinel a refined choice for collectors and custom commissions, its medium intensity greyish blue color responding well to creative metal pairings and diverse mounting architectures. Please contact The Natural Gemstone Company to discuss design sketches, metal options, recommended accent sizes, and fabrication methods, we can recommend experienced setters for tension, bezel, and micro pavé work, and we welcome requests for CAD renderings and mock ups to visualize the finished piece prior to production.
