1.00 Ct. Australian Color Change Sapphire ACC1009

This 1.00 carat Australian color change sapphire displays a fascinating dual personality — shifting from a deep royal blue under cool fluorescent light to a rich olive green under warm incandescent lighting. This natural phenomenon, known as color change, is highly prized among collectors and connoisseurs alike, making this gem a rare treasure.

Sourced from the gem-rich terrains of Australia, this sapphire is completely natural and unheated, retaining its authentic beauty and geological story. The stone features a well-proportioned oval mixed cut, which enhances its brilliance and provides a balanced silhouette — perfect for rings, pendants, or bespoke heirloom designs.
