1.54 Ct. Greyish Blue Star Sapphire from Ceylon (Sri Lanka)

This translucent greyish blue star sapphire weighs 1.54 carat and presents an elegant oval profile with dimensions of 7.15 x 6.00 x 3.15 mm. Cut as a classic cabochon, the gem retains a smooth domed surface and a well proportioned base that together emphasize depth and internal shimmer. Color intensity is graded as medium, offering a balanced and versatile greyish blue tone that adapts well to varied lighting conditions. The clarity is evaluated as very slightly included at eye level, indicating minor internal features that do not detract from overall appearance, and the finish is an excellent polish that yields a clean, reflective surface. This sapphire is natural and untreated, with no enhancement, and it originates from Ceylon Sri Lanka, a source renowned for producing material with attractive tone and fine optical effects.

The cutter has applied a considered geometric approach to the cabochon geometry, and this precise shaping functions in place of conventional faceting to optimize light interaction and asterism. The dome profile is carefully proportioned and centrally peaked to align with the crystal orientation so that the rutile needle networks that produce the star are presented to incident light in a controlled way. The result is a well defined star that moves crisply across the dome as the stone or light source is rotated. The geometric shaping of the dome and the symmetry of the oval outline promote maximum light play by guiding reflections across a clean, polished surface, and by enhancing contrast between the star and the surrounding body color. In addition the cutter has maintained a consistent girdle and base plane to preserve optical depth, allowing light to enter and be redirected by internal features before emerging as the characteristic luminous asterism associated with star sapphires.

Assessment of the stone emphasizes its practical and aesthetic attributes in use. At 1.54 carat this oval cabochon is well suited to a variety of mounting styles where the dome and star can be presented front and center, and the medium color intensity provides versatility for both modern and traditional settings. The very slight inclusions visible at eye level contribute to the natural character of the gem and play a role in the asterism, while the excellent polish enhances durability against surface wear and supports crisp light reflection. Origin from Ceylon Sri Lanka adds provenance noting a long history of sapphires with pleasing body color and distinct optical phenomena. For those seeking a star sapphire with natural origin and no enhancements, this piece offers a considered balance of tone, optical activity, and lapidary refinement. The Natural Sapphire Company presents this gem with standard gemological documentation and imagery that illustrate the stone on hand and in hand to show scale, face up appearance, and the behavior of the star under typical viewing conditions.
