VIEWING THE STAR

The star’s visibility, position, and definition depend on the light source and viewing angle. It may appear different under focused light compared with soft, diffuse lighting.

The supplied clarity description is eye clean. This describes its appearance to the unaided eye; it does not establish transparency or mean the gemstone is free of microscopic inclusions.

JEWELRY IDEAS

Consider a custom star sapphire ring, a bezel-set pendant, or a vintage-inspired design. Yellow gold can offer a warm contrast to purple, while white gold or platinum provides a cooler frame.

Ask your jeweler to check the gemstone’s orientation before setting so the star can be presented effectively. Choose a cabochon-compatible mount and confirm all three measurements, including the 4.70 mm height.
