1.13 Ct. Bluish Green Spinel from Ceylon (Sri Lanka)

This specimen is a transparent 1.13 carat oval bluish green spinel, precisely measured at 6.45 by 5.33 by 4.77 millimeters, exhibiting a refined mixed brilliant faceting scheme crafted to balance scintillation and color saturation. The mixed brilliant architecture features a brilliant cut crown with carefully calculated star and kite facets converging toward a crisp girdle, paired with a stepped pavilion that channels light back through the table to produce lively dispersion while concentrating the stone color. The pavilion depth relative to the average diameter is approximately 80.9 percent, a deliberate proportion that enhances face up color intensity while yielding a deeper visual presence, and the cutting proportions were executed to retain optimal light return given this depth profile. Clarity is graded as very very slightly included at eye level, indicating that inclusions are minute and require magnification to observe, and the polish is excellent across crown facets, girdle finish, and pavilion facets, resulting in clean facet junctions and crisp facet reflections. This spinel is entirely natural with no enhancement, originating from Ceylon Sri Lanka, a source known for producing delicately hued spinels with attractive light to medium saturation, and The Natural Gemstone Company provides full provenance information to support ethical sourcing and authenticity.

From an optical and physical standpoint this Ceylon spinel combines several attributes that make it a technically appealing engagement center stone. Spinel is a hard and durable gem material with a Mohs hardness of eight, making it resilient to the everyday wear expected of an engagement ring, and its isotropic crystal structure yields single refractive behavior, which means the gem shows consistent face up color without pleochroism. The refractive index of spinel in this compositional range is approximately 1.712 to 1.719, and its modest dispersion contributes to controlled fire when paired with the mixed brilliant facet design. The light bluish green hue presents with light color intensity, which on this particular cut is accentuated by the deeper pavilion, enabling the stone to read as both delicate and distinctly colored in daylight and artificial light. The very very slightly included clarity grade ensures that the stone is eye clean for typical viewing distances, while the excellent polish maximizes facet contrast and minimizes any surface irregularities that could scatter light. Because the pavilion is proportionally deep, the face up diameter will be slightly more modest than a shallow cut of equivalent carat weight, but the result is a concentrated, gem rich color that photographs and faces up with depth and character.

For engagement ring applications the combination of untreated natural origin, eye clean clarity, and a mixed brilliant cutting style offers both beauty and practical durability, making this spinel an exceptional alternative to traditional center stones. The oval outline provides classic elegance and elongates the finger, and the mixed brilliant design ensures lively scintillation from the crown facets while the stepped pavilion sustains color depth. Recommended settings include a four or six prong head to showcase the elongate silhouette while protecting girdle integrity, and a low bezel or partial bezel can be considered for clients prioritizing daily wear robustness, bearing in mind that a deeper pavilion may necessitate a setting that accommodates the lower profile or a recessed seat in the mounting. This bluish green tone pairs particularly well with warm metal choices such as rose gold to emphasize the green hint, and with platinum or white gold to create contrast through a diamond halo or pavé shoulders that increase perceived size and brilliance without competing with the core hue. At The Natural Gemstone Company we can provide detailed imagery under multiple light conditions, magnified analysis of inclusions, and setting mockups to demonstrate how this 1.13 carat oval spinel will present on the hand, and because the gem is natural and unenhanced we can also produce documentation of origin and treatment status to support provenance for a lifelong, meaningful choice.
