0.64 Ct. Violet Spinel from Ceylon (Sri Lanka)

This violet spinel from The Natural Gemstone Company is a transparent, well proportioned example of the species, presented in a classic cushion shape. The stone weighs 0.64 carat and measures 5.98 x 4.89 x 2.52 mm. It is faceted in a mixed brilliant cut that balances table facets with pavilion facets to optimize both brilliance and depth. The clarity is graded as slightly included at eye level, consistent with natural stones that retain a clean appearance when set with care. Color is described as intense, with a saturated violet tone that is neither overly dark nor pastel, and the finish exhibits an excellent polish. No enhancement has been applied, and the origin is Ceylon Sri Lanka, a region known for producing spinels with lively hues and reliable crystal quality.

The dimensions and cushion outline make this gem particularly well suited to custom jewelry applications. At just under 6 mm on the longest axis, the face up area provides a noticeable presence without dominating an overall design. The proportions yield a comfortable balance between spread and depth, with a 2.52 mm depth that allows for a low to moderate setting profile. For a ring, those measurements translate to an elegant center stone for slim to medium width bands, or a refined accent for multi stone designs. For pendants, the stone will read as a subtle focal point that sits close to the plane of the setting, reducing movement and wear. For earrings, the matching of two stones of this size would create a coherent pair that is wearable for daily use. The cushion shape itself provides softened corners and a slightly vintage aesthetic, facilitating settings that emphasize symmetry and light return, such as four prong profiles, low bezels, or a halo arrangement that enhances perceived size while protecting the girdle.

The mixed brilliant cut is an important practical consideration for custom work, because it delivers a balance of sparkle and color saturation. The crown facets contribute to scintillation and the perception of brilliance, while pavilion facets help to return light through the table, accenting the violet hue rather than washing it out. The clarity grade of slightly included at eye level indicates that inclusions are present but not dominant, permitting flexible design decisions. A competent lapidary or jeweler can orient the stone so that inclusions are less visible from the most likely viewing angles, or incorporate design elements that complement rather than conceal natural characteristics. The excellent polish enhances facet definition, which supports precise metal work and secure setting. The fact that the stone is untreated increases its long term stability and value, and the Ceylon provenance provides a useful datum for provenance documentation when creating bespoke pieces for collectors or for clients seeking traceability.

From a practical design perspective this spinel pairs well with a range of metals and complementary stones. Platinum or 18 carat white gold will harmonize with the cooler side of the violet tone, creating a modern, restrained look. Warmer metals such as 18 carat yellow gold can be used to introduce contrast, drawing out more purple blue undertones in the stone. For prong settings, a four or six prong approach will secure the cushion corners while maintaining maximum light exposure. Bezel settings can offer additional protection for everyday wear, and the shallow to moderate depth facilitates a low bezel that keeps the profile comfortable. Designers may elect to flank the spinel with small diamonds or color accent stones to increase perceived scale, or to set it alone as a minimalist statement that focuses attention on the intensity and natural character of the spinel. When commissioning custom work, plan for metal thickness and prong geometry that respect the stone dimensions of 5.98 x 4.89 x 2.52 mm to ensure a precise fit and to avoid stress on the girdle during setting.

In summary, this 0.64 carat cushion violet spinel from The Natural Gemstone Company represents a versatile, stable, and appealing option for custom jewelry projects. Its measurable face up size and balanced proportions suit a wide range of contemporary and classic settings, its mixed brilliant cut offers lively return of light while preserving rich color, and its slightly included clarity combined with excellent polish allows for thoughtful design decisions that either showcase natural character or minimize visibility of inclusions. The untreated nature and Sri Lankan origin provide additional assurance concerning durability and provenance, and the stone adapts well to rings, pendants, and earrings with predictable results for wearability and aesthetic integration. For clients and designers seeking a refined violet spinel that is ready to be the centerpiece of a bespoke creation, this specimen offers the technical qualities and visual appeal needed to translate design intent into a finished jewel.
