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

This listing describes one translucent, Other certified, Vivid Blue star sapphire, weighing 6.25 carats, presented by The Natural Sapphire Company. The gem is oval in outline and fashioned as a cabochon, with precise dimensions of 9.49 by 8.65 by 6.64 mm. The origin is Ceylon Sri Lanka, and the stone is accompanied by certification from Other. The lab color classification is Vivid Blue, and the stone exhibits intense color intensity. No enhancement has been applied, and the surface display is described as an excellent polish.

Optical and clarity attributes are consistent with a high quality collector grade star sapphire. The clarity has been graded as very slightly included when evaluated at eye level, and the body translucency allows a distinct asterism to form across the dome. The star presents as a sharp, well centered feature that responds cleanly to changes in light direction, indicative of strong oriented needle inclusions generating the effect. Cut proportions have been optimized for a balanced dome that supports the star while maintaining overall symmetry and table distribution. These technical qualities make the gem suitable for traditional star sapphire settings, where the cabochon form and visible asterism are the focal points. The description and measurements herein are provided to support objective assessment and to facilitate informed decisions about mounting and presentation.
