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

This listing describes one transparent bi color parti sapphire, of natural origin from Ceylon Sri Lanka, presented by The Natural Sapphire Company. The gem weighs 2.13 carats, and is fashioned in an emerald cut, with a faceted cutting style that emphasizes the stone structure and tonal separation. Its dimensions are 8.03 x 5.57 x 4.72 mm, producing a length to width ratio of approximately 1.44, and a depth of 4.72 mm which corresponds to a depth ratio of approximately 58.8 percent. The combination of an emerald step cut and these proportions yields linear facet planes that present color zoning with clarity, allowing the parti coloration to read distinctly across the table and step facets. The sapphire is transparent with a light color intensity, and its surface condition is described as excellent polish.

At 2.13 carats the sapphire occupies a premium category for parti and bicolor sapphires, where weight contributes both to visual presence and to the market rarity of untreated material with strong transparency. In practical terms this carat weight yields a stone that is substantial enough to function as a center gem for a wide range of rings and pendants while remaining compact enough to be set cleanly in classic or contemporary designs. The mass of 2.13 carats, combined with the emerald shape, provides a balance between table size and step faceting that enhances the perception of color separation without sacrificing brilliance. Clarity is graded as very slightly included evaluated at eye level, indicating that inclusions are minimal and do not materially interrupt the gem s overall transparency or the way the parti colors are read. The sapphire has not undergone any enhancement, which preserves its natural optical properties and confirms that the color and clarity are inherent characteristics originating in Ceylon Sri Lanka.

The cutting and finishing emphasize precision and restraint, with faceting executed to maintain symmetry and to allow the stone s internal features to contribute to its character rather than to obscure them. The emerald cut s step facets create an elegant hall of mirrors effect, particularly suited to bi color material where linear reflections can accentuate bands of color. An excellent polish ensures clean facet junctions and crisp light return across the table and crown facets, supporting both visual contrast and wearability. Given its dimensions of 8.03 x 5.57 x 4.72 mm the sapphire fits well into conventional prong, bezel, or channel settings, and its unenhanced status may be of particular interest to connoisseurs seeking natural material with documented origin. The Natural Sapphire Company presents this gem with specification grade information to assist in technical evaluation and design planning, and the details provided are intended to allow an informed assessment of the stone s suitability for intended jewelry applications.
