73.44 grams of natural, unheated Tanzanite perfection.

Some crystals demand your attention… this one refuses to give it back.

At an incredible 73.44 grams, this monster from the legendary Merelani Hills, Tanzania is a masterclass in pleochroism. Every slight turn unleashes a completely different personality—electric cobalt blues melt into vivid greens, flashes of golden yellow ignite across the crystal, while soft pinks and violets emerge from within. It feels like multiple gemstones captured inside a single crystal.

Completely natural and unheated, this specimen showcases the extraordinary beauty that has made Merelani tanzanite one of the most coveted collector minerals on Earth. The combination of exceptional size, rich saturation, sharp crystal form, and dramatic color play places this in a league of its own.

Mounted on a custom display stand, it’s a centerpiece that transforms with every change in light and every new angle.
