0.38 Ct. Bi Color / Parti Sapphire from Ceylon (Sri Lanka)

One transparent 0.38 carat emerald cut bi color parti sapphire, measuring 5.40 x 2.96 x 2.35 mm, presents a precise study in step cutting and material clarity, and this specimen from Ceylon is offered by The Natural Sapphire Company. The gem is faceted with an emerald cut that employs parallel step facets on the crown and pavilion to produce linear light return and controlled color zoning, and the cutting style emphasizes symmetry and parallelism in facet junctions to maximize the directional interplay of the two dominant hues. The stone evaluates as slightly included at eye level, with medium color intensity, and it bears an excellent polish, and there has been no enhancement to alter the natural color or structure. The emerald outline, coupled with a restrained table and proportioned crown height, frames the bi color transition so that each viewing angle reveals a different balance of tone, and the precise geometry keeps the surface reflections crisp rather than diffuse.

The technical virtues that read as near flawless in performance stem from the cutter s meticulous handling of angles and facet proportions, and the resulting optical behavior elevates the gem s beauty from every viewing direction. The step cut geometry is calibrated to control optical windows and light leakage, and the broad parallel facets act as planar mirrors that delineate the lighter and darker zones with high resolution, producing a clear, linear banding of color when the stone is rotated. Excellent polish minimizes surface scattering and preserves internal contrast, so the medium color intensity reads as saturated where the pavilion depth concentrates light, and as delicate and pastel where the crown allows more transmission. Slight inclusions remain characteristic of natural sapphires, and in this piece they do not disrupt overall transparency, instead serving as natural markers that confirm origin and authenticity while remaining unobtrusive under typical viewing conditions. The net effect is an apparent flawlessness in optical performance, a consistent crispness to facet edges, and a balance of contrast that makes the bi color expression legible from table down to pavilion facets.

From a craftsmanship perspective the cutter s decisions were oriented toward fidelity to the material s innate color zoning and to preserving weight while controlling proportions that influence face up color. The relatively shallow pavilion depth in combination with the elongated emerald format yields an elegant face up size for the 0.38 carat weight, and the parallelism of crown and pavilion steps creates repeatable reflections that emphasize the parti color morphology. Originally sourced from Sri Lanka, the sapphire exhibits the geological hallmarks of Ceylon material, where trace element distributions favor the medium intensity blues and violets present here, and the lack of enhancement preserves the natural chromophores and zoning that collectors prize. For settings, a mounting that exposes the pavilion with an open gallery will maximize the directional color shifts, while a low bezel or four prong design can be used to emphasize the stone s linear silhouette and to allow light to enter and exit the step facets freely. The Natural Sapphire Company offers this calibrated, well finished emerald cut bi color parti sapphire as a technically refined option for connoisseurs who value accurate proportions, excellent polish, and the authentic, unenhanced character of genuine Ceylon sapphires.
