3.27 Ct. White Star Sapphire from Ceylon (Sri Lanka)

This listing describes one translucent 3.27 carat oval white star sapphire offered by The Natural Sapphire Company, the gem measures 8.80 x 7.66 x 4.46 mm and is presented in a classic cabochon cut, the cabochon form emphasizes the stone face and allows the star to be visible across the dome, the shape is oval which provides a slightly elongated presentation and favorable proportions for many jewelry settings. The stone is colorless in intensity and presents as a white star sapphire, the surface polish is excellent which aids in the clarity of the asterism, clarity has been graded as very slightly included when evaluated at eye level, the specimen shows natural internal features that are typical for star sapphires, no enhancement has been applied to this material, and the documented origin is Ceylon, Sri Lanka.

Optically the gem displays a well defined six ray star under direct light, the asterism is produced by fine needle like inclusions that are aligned in intersecting orientations and the cabochon geometry combined with the internal silk results in a crisp star that becomes most apparent under a single point light source. The stone is translucent rather than fully opaque, this translucency allows for a pronounced star while still showing a soft body color that reads as white, the excellent polish reduces surface distortion and helps the star to track smoothly across the dome when the gem or light source is moved. The overall appearance is one of subtle sheen and focused asterism, the star is centered and proportionate to the cabochon profile which indicates careful cutting to align the internal silk with the dome axis.

From a gemological perspective this sapphire exhibits attributes that are consistent with natural, untreated material from Sri Lanka, Ceylon has a long history of producing well matched star sapphire material and this stone aligns with those expectations in terms of texture and optical behavior. The clarity grade of very slightly included at eye level indicates that any inclusions are minor and do not detract significantly from the visible star or overall appeal, microscopic examination reveals fine rutile silk rather than fractures or disruptive voids, the absence of enhancement confirms that color and translucency are wholly natural, durability is excellent for jewelry use since corundum rates 9 on the Mohs scale making it suitable for rings, pendants, and other daily wear pieces when set securely. The dimensions of 8.80 x 7.66 x 4.46 mm provide a substantial presence in hand without being overly large, the dome depth of 4.46 mm supports a strong asterism while keeping the profile moderate for typical mounting applications.

For practical use and long term care this white star sapphire can be set in a variety of mounting styles, a bezel setting will protect the edges of the cabochon and preserve the dome profile, a well designed prong setting can also present the stone with more visible side light for visual interest while ensuring secure retention, cleaning is best accomplished with warm water, a mild detergent and a soft brush, avoid harsh chemicals and sudden temperature extremes, professional ultrasonics may be used cautiously and only after consultation, given that no enhancement is present the stone does not require special treatment beyond standard care for corundum. The Natural Sapphire Company provides detailed imagery and measured specifications to support evaluation, additional photographs under point lighting and side views are available upon request to illustrate the asterism and to assist in design decisions, we also provide provenance information and gemological notes for clients seeking untreated, natural material.
