Star Blue Sapphire

Star Blue Sapphire is a captivating variety of sapphire that displays a natural star effect (asterism) across a rich blue body color. When viewed under a single light source, a luminous star—typically with six rays—appears to glide across the surface of the gemstone.

As a member of the corundum family, star blue sapphire has a hardness of 9 on the Mohs scale, offering excellent durability for everyday fine jewelry. These gemstones are traditionally cut as cabochons to maximize the star effect and are highly valued for rings, pendants, and collector pieces.

This category features carefully selected star blue sapphires chosen for strong blue color, sharp star definition, symmetry, and natural beauty.
