A cushion-cut sapphire from Tanzania’s Umba Valley, showing a rich violet-purple color with flashes of red and blue under light. The stone’s step-style faceting creates a broad window of brilliance while preserving depth in the bodycolor. Umba sapphires are known for their wide spectrum of colors, and this example highlights the stronger end of the purple range.
With a Mohs hardness of 9, sapphire remains one of the most durable choices for jewelry, while also offering collectors a chance to explore the diversity of corundum beyond traditional blue.
