If you are searching for a distinctive center stone for an engagement ring, or a rare, eye catching gem to complete a collector s cabinet, this Ceylon blue star sapphire answers that need with grace and presence. This translucent oval weighing 5.37 carats measures 10.55 x 9.37 x 5.58 mm, and its cabochon cut showcases a clear, centered star that moves like a beacon as the stone is turned.

Clarity is graded very slightly included, evaluated at eye level, which preserves the gem s natural character while maintaining excellent visual appeal. This gem has been heat treated to enhance its color stability, and it hails from Ceylon, the storied source of some of the world s most desirable star sapphires.
