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

This 1.85 carat cushion shape bicolor parti sapphire presents precise physical dimensions and a cutting profile that will interest technically minded buyers, dimensions 8.83 by 6.12 by 3.37 millimeters, faceted with a mixed brilliant cut, and an overall weight distribution that favors face up spread. The cutter has balanced a generous table with a well proportioned crown to accentuate scintillation while retaining a controlled pavilion, resulting in a measured depth of 3.37 millimeters which corresponds to approximately 45.1 percent depth relative to the average of length and width. This distribution produces an engaging appearance that reads larger than the carat weight alone might suggest, and the mixed brilliant facet scheme blends small step facets at the pavilion with brilliant facets on the crown to maximize both internal color zoning and bright reflective return. The stone is transparent and displays medium color intensity across its bicolor parti presentation, showing distinct but harmonized zones rather than abrupt banding, with pleochroic shifts visible on facet changes that the mixed brilliant architecture activates to provide changing visual interest from different viewing angles.

Clarity and finish are executed to a demanding standard, clarity graded as very slightly included when evaluated at eye level, which means inclusions are minimal, stable, and do not detract from the stone when set. The excellent polish and precise facet junctions contribute to strong light performance and a crisp facet pattern, which is particularly important in a parti stone where facet precision governs how the two tones interact and blend to the observer. The absence of any enhancement is a critical attribute from both connoisseur and investment perspectives, this sapphire is completely natural and untreated, which preserves original crystal character, silk distribution, and natural color saturation, attributes prized by advanced buyers. Origin Ceylon Sri Lanka is noted on provenance documentation, and this testimony to geographic source matters because light to medium blue and pastel color expressions from Ceylon are historically and commercially desirable, and the island s gemological signature often commands a premium in specialist markets, particularly when an untreated state is confirmed and the cutting style has been applied to reveal optimum face up color.

From an investment perspective this bicolor parti sapphire has several structural advantages that support potential appreciation, rarity economics are favorable in the segment of untreated, well cut Ceylon stones that display attractive bicolor character, supply is limited because most material undergoes heat treatment to refine uniform color, and untreated parti stones of attractive clarity and polish are infrequently available. The mixed brilliant cut in a shallow to medium depth profile enhances perceived size and makes the stone particularly appealing for collectors and high end jewelers seeking pieces that balance presence with optical performance, and collectors value both the visual uniqueness of parti coloration and the documentation of natural origin and lack of enhancement. Market drivers relevant to future price movement include continued demand for natural untreated gems, increasing emphasis on traceability and provenance, and the tendency for high quality, distinctive stones to outperform mass market material during periods of constrained supply. For buyers who prioritize investment attributes, we recommend obtaining laboratory documentation confirming untreated status and origin, considering secure insured storage, and using settings that protect the girdle and pavilion to preserve condition, since long term value correlates strongly with physical preservation and unaltered surface finish.

The investment case is further strengthened by liquidity considerations, well documented, natural Ceylon sapphires of this size and with top caliber cutting and polish attract interest across private collectors, auction houses, and high end retail channels, particularly when accompanied by professional photography and gemological reports. As with any tangible asset, diversification, proper documentation, and provenance are key, and partnering with a respected house enhances resale prospects, The Natural Sapphire Company offers detailed reports, access to reputable grading laboratories, and secure consignment pathways for clients seeking to realize long term appreciation. For clients focused on both connoisseurship and capital retention this 1.85 carat cushion bicolor parti sapphire represents a technically accomplished specimen with demonstrable rarity attributes and a cut that maximizes market appeal, and it stands as a candidate for inclusion in a curated gem collection or as the centerpiece of a bespoke commission intended to combine wearable aesthetics with an eye toward future value.
