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

This is a beautiful transparent 1.10 carat oval shaped bi color parti sapphire, measuring 7.99 x 5.26 x 3.22 mm, offered by The Natural Sapphire Company. The stone is faceted with a mixed brilliant cut, which combines the scintillation of brilliant facets along the crown with step like facets on the pavilion to deliver both lively sparkle and deep, controlled light return. At 1.10 carats the proportions are well balanced for this oval outline, allowing the pavilion depth to be sufficient for color saturation while maintaining an elegant face up size. The clarity grade is described as very slightly included when evaluated at eye level, meaning the sapphire reads clean to the naked eye in ordinary viewing, with only minor internal features that do not interfere with transparency or brilliance. The polish is excellent, which maximizes the stone s ability to reflect light and enhances its visual appeal in both direct and diffused lighting. The medium color intensity and natural bi color distribution, showing a harmonious interplay between yellow and blue tones, create an engaging parti effect that shifts with changing angles and lighting conditions.

From a gemological perspective this sapphire presents several factors that educated buyers will recognize as positive for both beauty and long term desirability. The mixed brilliant cut is selected to optimize both color and fire, and the excellent polish confirms expert lapidary execution. The clarity evaluation at eye level as very slightly included indicates that the stone will present well in most settings without the need for magnification to assess quality. This sapphire has been heat treated, a widely accepted and stable enhancement in the sapphire trade, used to improve color uniformity and clarity. Full disclosure of heat treatment is provided, and the treatment does not diminish the material s natural origin or structural integrity. Origin is Ceylon, Sri Lanka, a locality with a storied reputation for producing sapphires noted for their clarity, attractive color ranges, and gemological character. Ceylon material has been sought after for centuries for both fine jewelry and museum grade specimens, and this parti example displays the provenance qualities collectors associate with that tradition.

When compared to famous gemstones in history, this stone should be appreciated for its unique role rather than as a large historic icon. Ceylon sapphires have a lineage that includes some of the most celebrated examples in public and private collections, and while those legendary stones are often remarkable for size or singular color, this parti sapphire offers a different kind of rarity. The dual coloration of parti sapphires sets them apart from uniform blue sapphires such as Kashmir stones, and from padparadscha sapphires which are prized for a singular salmon pink hue. Parti sapphires are admired for their natural zoning and pleochroic behavior, which create dynamic color interplay that can be worn and appreciated as both a modern aesthetic and a collector s curiosity. In historical perspective, collectors have valued stones for exceptional color, cut, and provenance, and this gem brings a combination of expert cutting, fine polish, clean appearance, Ceylon origin, and a visually arresting bi color phenomenon. That combination makes it interesting to connoisseurs who value narrative and gemological distinctiveness as much as raw size or single color purity.

For the educated buyer this sapphire represents a collectible and wearable gem with clear, disclosed attributes that support confident purchase decisions. The 1.10 carat weight and oval mixed brilliant cut make it suitable for a variety of fine jewelry settings, including solitaire rings, bespoke pendants, and elegant halo designs where the parti coloration can be showcased. The very slightly included clarity ensures that the stone appears lively and transparent without distracting inclusions, and the excellent polish enhances both brilliance and durability of the finish. Heat treatment is an industry standard enhancement, and because it is fully disclosed the buyer has accurate information for valuation and insurance purposes. Provenance from Ceylon adds historical and market appeal, and The Natural Sapphire Company provides open disclosure and documentation to support that provenance. For collectors and buyers who prioritize rarity of color, thoughtful cutting, and verified origin, this bi color parti sapphire is a distinctive choice that balances visual interest with sound gemological credentials.
