2.91 Ct. Blue Star Sapphire from Burma (Myanmar)

One attractive translucent blue star sapphire, weighing 2.91 carats, is presented with an oval outline and precise measurements of 8.47 x 7.42 x 4.35 mm, offered by The Natural Sapphire Company. The gem is fashioned as a cabochon, the classical shape for asteriated sapphires, and it exhibits an intense color intensity with a vivid, saturated blue that remains evenly distributed across the dome. Clarity is graded as very slightly included evaluated at eye level, with fine internal features that contribute to the star phenomenon without detracting from the overall uniformity of the color. The surface finish is described as excellent polish, providing a clean, reflective dome that supports a crisp and well defined star. There has been no enhancement applied to this stone, and its origin is recorded as Burma, Myanmar, a historic source known for producing a wide range of fine blue sapphires.

From a gemological perspective, the asterism is the defining attribute of this specimen, and it is produced by oriented needle like inclusions that intersect to form a coherent, six ray star when the cabochon is cut with symmetry and proper dome height. Under a single point light source the star appears distinct and centralized, and under broader lighting conditions the star remains visible though its contrast may vary with the light angle and intensity. The translucency of the host material permits the star to float near the surface, while the excellent polish enhances the star contrast and overall brilliance. The cabochon geometry, including its dome height and oval outline, has been executed to maximize star mobility while maintaining an attractive silhouette suitable for a variety of settings. The internal inclusions are fine and dispersed, sufficient to create a pronounced asterism without heavy cloudiness, which supports both aesthetic appeal and practical wearability.

In terms of physical properties and considerations for use, this sapphire benefits from the inherent hardness and durability of corundum, which makes it suitable for daily wear in rings, pendants, and other jewelry, provided standard protective measures are observed. For settings, designs that present the dome to light sources are recommended to showcase the star, and a bezel or protective gallery may be employed to safeguard the edges of the cabochon. Mounting decisions should take into account the oval proportions and the desire to align the star with the intended orientation in the finished piece. Cleaning may be performed with warm water, mild detergent, and a soft brush, rinsing thoroughly and avoiding prolonged exposure to harsh chemicals. While corundum is stable under typical cleaning and wearing conditions, professional advice is recommended for high temperature or chemical exposures, and ultrasonic cleaning or steam cleaning should be used only with caution and professional assessment.
