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

This listing describes a transparent 0.70 carat pear shape bi color or parti sapphire, with precise dimensions of 6.76 x 4.63 x 3.17 mm. The stone is faceted in a mixed brilliant cut, combining facet arrangements that optimize both brilliance and dispersion. Clarity is graded as slightly included when evaluated at eye level, and polish is rated excellent. There has been no enhancement to this material, and its documented origin is Ceylon Sri Lanka. The Natural Sapphire Company presents these technical characteristics to provide a clear and objective foundation for assessment and setting decisions.

The bi color or parti character of this sapphire creates a distinctive color distribution, exhibiting a range from more saturated blue tones to softer, paler areas within a single crystal. The medium color intensity ensures that the hues remain vivid without becoming overly dark, which supports versatility across different jewelry applications. Under direct light the color zones display lively contrast, and under softer illumination the tones blend in a pleasing gradient. This interplay of color and light gives the stone a vibrancy that will stand out in any jewelry setting, producing visible depth and interest when viewed from multiple angles.

Cut quality and proportions have been selected to enhance the stone face up appearance and overall light return. The pear shape provides an elegant silhouette that elongates when set in rings or pendants, and the mixed brilliant faceting balances scintillation with broad flashes of light. The table size and depth expressed by the 6.76 x 4.63 x 3.17 mm proportions maintain sufficient depth for internal reflections while preserving an attractive face up surface. Facet junctions and symmetry are carefully executed to support even light performance, and the excellent polish promotes crisp reflections and clarity of color. Orientation within a mounting will influence which color zones are most prominent, allowing for considered design choices that emphasize the desired visual effect.

Slight inclusions are consistent with natural sapphire formation and do not materially impact the structural integrity of the gem when properly set. At eye level these inclusions are modest, and the overall transparency supports clear observation of the internal color interplay. For daily wear, protective settings that shelter the pointed end of the pear and limit exposure to hard knocks are recommended. The absence of heat or other enhancement affirms the natural state and provenance from Ceylon Sri Lanka, information that is supported by The Natural Sapphire Company documentation. Care recommendations include routine gentle cleaning with warm water and mild detergent, avoiding ultrasonic or steam cleaning if inclusions are a concern, and periodic professional inspection of the mounting.
