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

This cushion shaped bicolor parti sapphire presents a commanding presence as a three point zero nine carat gemstone, with face up dimensions of eight point eight two by six point seven three millimeters and a measured depth of four point seven six millimeters. The proportions yield an approximate depth ratio of sixty one percent, a proportion that balances a generous table with sufficient pavilion height to promote both internal reflection and depth of color. Cut in a faceted, mixed brilliant style, the gemmaker has executed a modified brilliant crown with a series of kite and triangular facets above the girdle, paired with a pavilion that incorporates controlled step style facets and elongated keels to concentrate and release light in measured flashes. The cushion outline increases the perceived spread compared with a round of similar carat weight, delivering a larger face up area that is ideal for statement jewelry where visual impact and surface presence are priorities.

The faceting strategy employs symmetry and facet junction precision to manage the parti color distribution, the cutter intentionally oriented the pavilion and crown axes to showcase the bi color transition while preserving scintillation. The mixed brilliant approach combines the scintillating return of brilliant cut geometries on the crown with the color enhancing properties of broader pavilion facets and girdle realm reflections, producing a lively interplay between pinpoint scintillation and broader flashes of body color. The gem displays vivid color intensity, which in a sapphire of this origin translates to saturated hue that reads strongly in both transmitted and reflected light. Polishing has been assessed as excellent, providing crisp facet planes and clean facet junctions that support high contrast between light and dark areas, a necessary condition for a stone designed to be the focal point in a design.

Clarity is graded as very slightly included, evaluated at eye level, a classification that indicates the inclusions are minor and do not materially obstruct transparency or brilliance when viewed unaided. Under loupe inspection the inclusions are typically confined to localized zones or reside near facet intersections, which in many instances can act as optical anchors that actually enhance the character of a parti sapphire by delineating color boundaries without being intrusive. From a setting and design perspective the combination of eye level clean appearance and three point zero nine carat mass means the gem reads as both visually clean and durable, suitable for rings, pendants, and brooches where the wearer and designer want a single stone to command attention. Because the stone is heat treated, a standard and stable enhancement for Ceylon material, the color saturation and clarity have been optimized while preserving the natural crystal structure and pleochroic behavior characteristic of corundum.

Provenance from Ceylon, Sri Lanka, speaks to the classic gemological qualities buyers expect from the region, namely lively tone and vivid saturation combined with fine crystalline transparency. The Natural Sapphire Company presents this sapphire with full disclosure of its treatment and origins, enabling informed decisions about design and setting. For technical settings a four to six prong head that maximizes light entry through the crown, or an open gallery pendant that permits light through the pavilion, will exploit the mixed brilliant architecture to its best effect. A low bezel that reveals the girdle and pavilion reflections can preserve the stone s natural play of color, while a halo of smaller accent stones can amplify perceived size without diminishing the bicolor effect. In every application the stone s size, precision of cut, and eye level clarity make it an exemplary choice for a statement piece where technical quality and visual drama are equally valued.
