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

One transparent 1.22 carat oval greyish blue spinel, dimensions 7.64 by 5.63 by 3.89 mm, offers a balanced presence for a wide range of custom jewelry designs. The gem presents an oval outline that measures comfortably within the standard proportions for ring center stones, and the moderate depth provides a pleasing face up area while maintaining good light return. Origin documented as Ceylon Sri Lanka, this spinel is presented in its natural state, with no enhancement, providing confidence in both provenance and treatment history. The clarity is graded as slightly included when evaluated at eye level, which means the inclusions do not dominate the visual appearance, and the high transparency allows the greyish blue hue to appear consistent across the table and crown facets.

The cutting style is faceted, executed with a mixed brilliant cut, combining a brilliant crown with a step influenced pavilion geometry to optimize both sparkle and color distribution. This approach enhances the gem efficiency, producing scintillation that complements the stone intensity, without compromising its refined tonal character. The polish has been evaluated as excellent, yielding crisp facet junctions and strong light return, attributes that are particularly important for gemstones intended for close wear and detailed settings. The intense color intensity of this spinel gives the stone a strong presence, and the greyish blue tone provides versatility, pairing effectively with both warm and cool metal palettes.

For custom jewelry, the oval shape and the specific measurements of 7.64 by 5.63 by 3.89 mm make this spinel an especially practical choice. In ring applications, the stone occupies a visual space that is substantial enough to serve as a memorable center stone, while remaining comfortable for everyday wear. The elongated form of an oval offers visual length on the finger, and this size allows designers to explore both solitaire and halo variations, as well as three stone and split shank concepts. The symmetry and well proportioned girdle allow settings that emphasize the face up color, and the mixed brilliant cutting style supports designs that rely on dynamic light performance rather than sheer size alone.

Beyond rings, the measured dimensions and cut quality make this spinel well suited for pendants and drop earrings, where the oval outline provides classic elegance and the intense color maintains presence in smaller compositions. In pendant work, the stone offers a refined focal point that pairs cleanly with bezel or prong settings, and the excellent polish will ensure it reads well under ambient lighting. For earrings, matching pairs can be created using complementary stones or by mirroring with diamonds or sapphires, capitalizing on the spinel color to add depth and contrast. Jewelry designers will find that this gem adapts to a variety of metal choices, as the greyish blue hue harmonizes with platinum and white gold for a cool contemporary look, and with yellow and rose gold for a modern contrast.

The Natural Gemstone Company presents this spinel as a high quality, unenhanced natural material ideal for bespoke commissions and small batch designs, offering both aesthetic appeal and practical dimensions for precision setting work. When planning a custom piece, consideration of the stone depth at 3.89 mm is important for bezel clearance and prong design, and the slightly included clarity grade should be taken into account when positioning the stone to present the cleanest face up window. Care recommendations include routine gentle cleaning and professional inspection of settings to maintain the integrity of the gem in daily wear. For designers and clients seeking a naturally sourced spinel with strong color intensity, reliable cutting, and a versatile oval format, this 1.22 carat Ceylon spinel represents a well documented and adaptable option, and our team at The Natural Gemstone Company is available to provide additional technical measurements or guidance for setting the stone in a custom design.
