Nature absolutely showed off with this one.

This 40.13 gram natural, unheated Tanzanite is the definition of collector grade. As it turns in the daylight, the crystal comes alive—shifting effortlessly between rich cobalt blue, electric violet, and deep flashes of burgundy. That incredible pleochroism is exactly what makes fine Tanzanite so captivating.

Untouched by heat, this crystal displays the beauty that formed naturally beneath the earth over millions of years. Clean, sculptural, and full of life from every angle, it’s the kind of specimen that commands your attention the moment you pick it up.

These are the pieces that remind me why the hunt never gets old. Every great crystal tells its own story—and this one speaks for itself.
