0.38 Ct. Spinel from Ceylon (Sri Lanka)

This specimen is a transparent blue spinel weighing 0.38 carat, presented in an elegant oval shape with dimensions of 4.78 by 3.97 by 2.75 millimeters. The gem displays an intense blue color intensity and an exemplary level of transparency. The cut is a mixed brilliant cut, executed to balance surface brilliance with internal light return, and the finish is noted as excellent polish. Clarity is graded as very very slightly included, evaluated at eye level, indicating that field of view inclusions are negligible and do not detract from the gem's overall visual performance. This spinel is of natural origin from Ceylon, Sri Lanka, and it has not undergone any enhancement, preserving its natural character and value. The Natural Gemstone Company provides this stone as a ready to set piece for makers and collectors who prioritize natural origin and minimal intervention in their gemstones.

The color of this blue spinel is a defining characteristic. It presents a saturated, intense blue that remains balanced rather than overly dark, offering depth without losing the capacity to interact with light. The mixed brilliant cut enhances the stone's color by facilitating even light distribution across the pavilion and crown facets, producing controlled brilliance and scintillation. Because the gem is transparent and finely polished, it returns light with clarity and a lively play of small flashes. These optical attributes make the spinel adaptable in design contexts where true color and a consistent visual presence are desired, including everyday pieces that require a resilient appearance and formal jewelry that benefits from a strong focal hue.

Proportions and clarity make this gem particularly versatile for settings. With a depth that measures 2.75 millimeters relative to an average diameter of approximately 4.38 millimeters, the depth ratio is about 63 percent, a proportion that supports stable setting options and good durability when mounted. The very very slightly included clarity grade means that inclusions are minimal and typically not visible without magnification, assuring a clean face up presentation in common mounting styles. The mixed brilliant cut is well suited to both prong and bezel settings, providing secure girdle dimensions and favorable facet geometry for light return. The excellent polish contributes to smooth facet junctions and crisp reflections, characteristics that facilitate stone setting and handling during post mounting finishing.

In practical application this 0.38 carat oval blue spinel offers broad versatility, functioning equally well in casual and formal contexts. Its size and weight are appropriate for delicate solitary rings and pendants, and the intense color allows it to act as a striking center in minimalist designs. For more elaborate settings it performs reliably as a primary stone in small cluster rings, stud earrings, or as the colored focal point of a halo composition. The stone pairs attractively with a range of metal choices, including white gold, platinum, yellow gold, and rose gold, enabling designers to tailor the final presentation to the intended wardrobe use. Care for this spinel is straightforward, following standard nonabrasive cleaning methods and avoidance of harsh chemical exposure to preserve polish and color. For professionals and collectors seeking a naturally sourced, unenhanced blue spinel with proven optical and physical attributes, this piece from The Natural Gemstone Company offers documented origin, precise measurements, and a balance of color, clarity, and cut that translates well across a wide spectrum of jewelry applications.
