Product Description

CODE20

A striking 0.99 carat Natural Black Star Sapphire, fashioned into a classic round cabochon to showcase its captivating natural optical phenomenon. This gemstone exhibits a deep black to dark gray body color with a subtle silky sheen, allowing the star effect to become visible under a focused light source.

Unlike faceted sapphires, star sapphires are valued for asterism—a rare phenomenon created by microscopic rutile inclusions that produce a luminous star gliding smoothly across the surface as the gemstone moves. This unique optical effect makes every star sapphire a distinctive collector's gemstone.

Its nearly one-carat weight and symmetrical round cabochon cut make it an excellent choice for custom rings, pendants, talismans, and one-of-a-kind jewelry creations.

As a member of the prestigious corundum family, this gemstone offers exceptional durability with a Mohs hardness of 9, making it suitable for everyday wear while maintaining its beauty for generations.
