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

This transparent, bi color parti sapphire weighs 1.32 carat, and presents an emerald cut faceted form with dimensions of 6.99 x 5.49 x 3.70 mm. The stone displays light color intensity, with a subtle and balanced interplay of pale blue and warm golden tones that shift with viewing angle and light source. Clarity is graded very very slightly included at eye level, indicating minimal internal features that do not detract from overall transparency or brilliance. The cutting style is precise, with an emerald cut geometry that emphasizes linear facets and step style reflections, and polish is evaluated as excellent, producing clean facet junctions and smooth reflective planes. The sapphire is natural and untreated, enhancement status none, and origin is Ceylon Sri Lanka, a source known for its historical and consistent production of fine sapphires. The gem is suited to designs that favor clean lines and understated color complexity, and measurements are provided to assist in mounting and design planning.

The journey from mine to market for this sapphire began in the metamorphic alluvial fields of Ceylon Sri Lanka, where small scale and artisanal mining methods commonly yield rough material. After extraction, the rough crystal was logged, photographed, and carefully cataloged to preserve provenance information, and then subject to preliminary washing and sorting to remove matrix and surface material. Visual inspection and loupe analysis guided the selection of rough pieces suitable for faceting, identifying this piece for its clarity and bi color zoning. The selected rough was then entrusted to an experienced lapidary who planned the emerald cut to maximize transparency, minimize waste, and balance the distribution of the two color zones. Precision sawing and preforming established the general outline, followed by step faceting to create the characteristic table, crown, and pavilion geometry. Throughout cutting, attention was given to facet alignment, symmetry, and retention of weight, and finishing stages included progressive grits and final polishing to achieve the excellent surface quality observed. Prior to market listing the gemstone underwent standard gemological verification, including visual microscopy to confirm clarity and to document natural inclusions, and origin assessment based on inclusions and trace element consideration consistent with Ceylon Sri Lanka material.

The Natural Sapphire Company presents this sapphire with complete measurements, weight, and descriptive grading, and provides photographic documentation that illustrates its bi color character and facet structure. The stone is offered as a natural, untreated gem, which is a material distinction of importance to designers and collectors who seek authentic, stable color and clarity without enhancement. With its emerald cut proportions and very very slightly included clarity, the sapphire is especially appropriate for bezel or stepped gallery settings that complement its linear facet architecture, and the dimensions 6.99 x 5.49 x 3.70 mm allow accurate planning for prong count and seat depth. Durability is inherent to sapphire as corundum class material, making the stone suitable for daily wear in rings and other jewelry where resistance to abrasion is desirable. For those specifying a gemstone based on origin, clarity, cut, and treatment status, this piece provides a clear, verifiable profile, and The Natural Sapphire Company can supply additional imaging, certification options, and provenance documentation to support confident selection and commissioning of a finished setting.
