45.17 grams of absolute Tanzanite insanity…

Natural. Unheated. Completely electric.

This monster crystal is loaded with insane record keepers and some of the strongest pleochroism I’ve ever seen in a Tanzanite — shifting effortlessly between deep cobalt blue, rich violet, flashes of burgundy, and glowing teal depending on the angle and light.

The crystal quality is next level… super gemmy with incredible transparency, sharp structure, and internal depth that keeps pulling your eyes deeper into the piece. And those natural record keepers across the faces just take it to another level entirely — tiny geological signatures frozen in time.

Elite unheated Tanzanite at this size and quality is becoming seriously difficult to source, especially crystals with this much optical performance and character.

One of those pieces that feels alive in hand.
