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

This exquisite transparent 1.61 carat round bi color parti sapphire from The Natural Sapphire Company combines precise cutting and pleasing proportions with a striking and unusual color presentation, making it immediately appealing to both connoisseurs and discerning jewelry designers. The gem measures 6.65 by 6.60 by 5.15 millimeters, and it is faceted in a mixed brilliant cut, a style selected to maximize internal brilliance while preserving the stone weight and accentuating color separation. The cutter achieved an excellent polish which enhances light return and surface luster, and the stone presents an intense overall color intensity that shifts between two complementary hues across the pavilion and crown. The clarity grade is very slightly included as evaluated at eye level, a designation that signals the stone is visually clean to most observers while retaining natural characteristics that confirm its natural origin. The combination of transparency, intense color, and careful cutting produces a lively gem with a balance of sparkle and color depth that is rare for bi color material.

The origin of this sapphire is Ceylon Sri Lanka, a provenance that carries significant historical and gemological weight and that materially affects both desirability and market value. Sri Lanka has produced some of the most celebrated sapphires in the industry, and its alluvial deposits and metamorphic host rocks are known to yield stones with exceptional color saturation and attractive pleochroism. For blue and green tones, trace element chemistry including iron and titanium contributes to the hues that define the gem, and the particular environmental conditions in Ceylon often produce clean, transparent crystals that respond very well to careful cutting. Region of origin matters to educated buyers because it informs expectations about color behavior, clarity tendencies, and treatment norms. In this instance the sapphire has been heat treated, a widely accepted and stable enhancement that improves color saturation and reduces certain inclusions, and the treatment is fully disclosed. The Natural Sapphire Company confirms origin through established sourcing practices and documentation, and the Ceylon provenance enhances the stone value relative to comparable material from less renowned sources.

For an informed buyer the value proposition of this stone rests on several measurable attributes, and each of these is favorable in this example. The mixed brilliant cut is chosen deliberately to reconcile the needs of a multi toned stone, enabling a lively face up appearance while allowing the bi color nature to remain visible as a design feature. The clarity grade of very slightly included ensures that the gem reads as clean and offers unhindered light performance, while the intense color intensity gives the stone presence in both solitaire and accent settings. Heat treatment when disclosed and properly executed is a standard trade practice that stabilizes and enhances the gem without diminishing its long term appeal. The Ceylon origin adds provenance value and is of particular interest to collectors and designers seeking authentic, classic sapphire character. From a practical perspective this sapphire will perform beautifully in bespoke engagement pieces or in sophisticated modern settings where the bi color quality becomes a focal element, and The Natural Sapphire Company stands behind the stone with professional grading information and responsible sourcing practices, providing buyers with the transparency and confidence they expect when selecting a gem of this quality.
