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

This oval shaped bi color parti sapphire presents a clear and measured set of gemological attributes, suitable for both careful appraisal and selective acquisition. The stone weighs 1.39 carat, and measures 7.34 x 5.74 x 3.96 mm, with a faceted surface that employs a mixed brilliant cut to balance fire and brightness. The material is transparent, with light color intensity that reveals subtle shifts across the blue and near colorless zones characteristic of parti colored sapphires. Clarity has been evaluated at eye level and is graded as very slightly included, a level that preserves visual appeal while indicating natural origin. Polish on the facets is excellent, contributing to the gemlets overall light return and surface finish. Importantly, the sapphire has no enhancement, a distinction that affects both aesthetic assessment and market positioning. The Natural Sapphire Company provides this precise description to support informed evaluation and to document the stone as an untreated example from a recognized source.

Origin and cutting influence are central to this sapphires profile. The stone originates from Ceylon Sri Lanka, a provenance that has historical significance in the trade for both quality and stylistic expectations. Sri Lankan sapphires are known for their range of tones and for producing material that responds well to precise cutting methods. The mixed brilliant cut on this oval shape has been selected to maximize brilliance while preserving weight and measuring proportions that suit many jewelry settings. The dimensions 7.34 x 5.74 x 3.96 mm place the gem in a size class that is versatile for rings and pendants, while the bi color parti character increases its distinctiveness. The combination of a clean appearance at eye level and an excellent surface polish supports wearing durability when set responsibly, and it also impacts perceived value in the secondary market.

Investment potential and the prospect of future appreciation should be considered within a framework of objective factors that influence colored gemstone values over time. Untreated natural sapphires command a pricing premium relative to heat treated or otherwise enhanced material, because they are rarer and because provenance and natural color zoning are preserved. The fact that this sapphire is untreated and originates from Ceylon Sri Lanka contributes positively to its long term collectability. Parti colored sapphires occupy a niche that can appeal to collectors seeking unique color dynamics, which can enhance demand for particularly attractive examples. Equally important are supply side dynamics, which include the variability of production from traditional sources, the relative scarcity of larger clean stones in this category, and market shifts driven by collector taste and designer interest. These elements can foster appreciation, yet appraisal must remain measured. There are no guarantees with any gemstone investment, and liquidity will vary depending on market conditions, the quality of documentation, and the presence of an established provenance.

Practical considerations support the assessment of this sapphire as a considered acquisition for those seeking both aesthetic value and potential long term appreciation. Documentation from The Natural Sapphire Company, including detailed measurements, clarity grading, origin attribution, and confirmation of no enhancement, is an important component of market acceptability and resale readiness. Proper setting and care will preserve the stones condition and thus its market value. Professional appraisal, appropriate insurance, and secure storage or display when not worn are prudent measures for owners. For those considering an investment orientation, a focus on stones with confirmed untreated status, clear documentation, and recognized origin will generally provide stronger resilience in value. This 1.39 carat oval bi color parti sapphire exemplifies those characteristics, presenting a balanced combination of natural color interest, transparent clarity when viewed at eye level, and craftsmanship in cut and polish, as documented by The Natural Sapphire Company.
