4.04 Ct. Blue Star Sapphire from Ceylon (Sri Lanka)

This translucent blue star sapphire weighs 4.04 carats, and it is presented in an oval outline measuring 8.97 x 8.14 x 5.91 mm. The gem has a double cabochon cut, with smooth domes that are crafted to enhance asterism, and the polish is excellent. Color is described as light in intensity, yielding a soft, even blue that complements the stone clarity. Clarity is graded very slightly included evaluated at eye level, with minor internal features that do not detract from the overall appearance, and these oriented needle like inclusions are responsible for the visible star phenomenon when the stone is properly illuminated. The star is distinct and well defined under directional light, and the combination of translucency and a well executed double cabochon shape produces pleasing movement and depth as the gem is rotated.

This stone is GIA certified, and the report notes origin as Ceylon, Sri Lanka, with no indication of enhancement. The lack of treatment retains the natural silk and internal texture characteristic of classic Ceylon star sapphires, and the documented enhancement status provides objective verification for collectors and designers. At 4.04 carats and with balanced oval proportions, the sapphire is suitable as a focal gem in a pendant or a ring, where closed back or partial bezel settings can both protect the cabochon profile and present the asterism to advantage. Care recommendations include gentle cleaning with warm soapy water and a soft brush, avoiding harsh chemicals and abrasive contact to preserve the polish and domed surfaces.
