0.37 Ct. Spinel from Ceylon (Sri Lanka)

This 0.37 carat oval shape blue spinel from Ceylon is presented with exacting attention to proportion and finish, and dimensions of 4.81 by 4.07 by 2.77 mm. The gem is faceted in a mixed brilliant cut that balances a faceted crown with a precise pavilion geometry to maximize return of light and create controlled scintillation. Transparency is excellent, with an intense color intensity that presents a clear and appealing blue that reads consistently across viewing angles. Clarity is graded slightly included as evaluated at eye level, and these internal features are subtle and unobtrusive when the stone is set or viewed in hand. The surface receives an excellent polish that removes any microabrasions and presents a mirror like finish to the eye. There has been no enhancement of this spinel, and its natural origin is Ceylon, which contributes to the gemological character and provenance valued in fine colored stones. The Natural Gemstone Company describes this specimen with precise measurements and accurate assessment to support informed selection.

The combination of cut precision, strong polish, and transparent body produces what may be described as a visually flawless face up appearance, and this quality enhances the gem from every angle. The mixed brilliant facet arrangement directs light into the pavilion and returns it through the crown in a series of bright flashes and deep blue areas, so motion and changes in perspective reveal rhythmic shifts between sparkle and saturated color. Excellent polish removes surface interference that can dull luster, allowing crisp facet junctions and sharp facet planes to act together and render clean reflections and distinct contrast. Even with slight internal inclusions, the transparency and facet design minimize their visibility at normal viewing distances, so the gem displays an intact field of color and uninterrupted brilliance. The lack of treatments preserves the natural optical properties and makes the stone suitable for close setting work where cut and finish will be the primary contributors to appearance. For professional jewelry design and collecting, this blue spinel offers dependable performance in settings where every angle is visible and every surface must contribute to overall beauty.
