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

This translucent white star sapphire weighs 1.12 carats and is fashioned into an oval cabochon with precise dimensions of 5.83 by 4.82 by 3.60 mm. The cabochon cut is executed to emphasize a centered asterism and to preserve weight, exhibiting an even domed profile and excellent polish that enhances light return across the surface. Color intensity is near colorless, exhibiting subtle cool tones when viewed against neutral backgrounds, and clarity is graded as very slightly included when evaluated at eye level, with internal silk alignments visible under magnification that contribute positively to the star effect rather than detract from overall transparency. There has been no enhancement applied to this stone, and the provenance is Ceylon Sri Lanka, a classic source known for well formed star sapphires and consistent crystallographic quality.

From a lapidary and gemological perspective this piece demonstrates meticulous alignment of the cabochon axis to the underlying crystal habit, a critical factor for clean asterism in corundum. The star is produced by oriented rutile silk within the corundum matrix, and the cutter has chosen a dome height and symmetry that favour a sharp, mobile star under directional lighting, while maintaining a balanced outline suited to classical settings. The excellent polish reduces surface diffusion of light and clarifies the contrast between star and body, important for collectors assessing optical phenomena. With corundum hardness of 9 on the Mohs scale, this sapphire offers durable wearability, and it is particularly well suited to bezel or secure prong settings that protect the high dome and showcase the star. At The Natural Sapphire Company we document origin and treatment status for every gem, and this Sri Lankan white star sapphire is presented as a natural, unenhanced example of fine craftsmanship and optical complexity, ideal for connoisseurs who prioritize provenance, cutting technique, and the intrinsic interplay of inclusions that create stellar effects.
