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

This listing describes one translucent 1.79 carat oval greyish blue star sapphire, dimensions 7.14 x 6.56 x 3.97 mm, cabochon cut, originating from Ceylon, Sri Lanka, and supplied by The Natural Sapphire Company. The gem displays a medium light color intensity with a cool greyish blue tone that is evenly distributed across the stone. The cabochon has been shaped with a rounded dome to optimize asterism, producing a clear, centered star that becomes most distinct under a single overhead light source. Clarity is graded as slightly included, evaluated at eye level, with fine internal features characteristic of natural star sapphires. The stone has an excellent polish, contributing to strong luster and unobstructed visibility of the star. No enhancement has been applied to this sapphire, the specimen is natural and untreated.

From a gemological perspective, the combination of translucency, cabochon profile, and internal silk structures yields a pleasing star effect without compromising surface appearance. The dome height of 3.97 mm and the oval outline measuring 7.14 by 6.56 mm offer practical proportions for secure mounting in a variety of jewelry settings, including rings, pendants, and brooches, where the star can be oriented to display its asterism properly. Slight inclusions are consistent with natural origin and contribute to the formation of the star, they do not detract from the overall appeal when viewed face up. The excellent polish ensures durability and ease of cleaning, recommended with gentle warm soapy water and a soft brush, avoiding harsh chemicals and ultrasonic cleaners to preserve the cabochon surface. This Ceylon star sapphire represents a natural, elegant example of asteriated sapphire, presented with clear, factual specification and condition information by The Natural Sapphire Company.
