91.55 grams of Merelani royalty.

Some Tanzanites are beautiful. Others become the benchmark by which every future crystal is judged.

This 91.55 gram natural, unheated Tanzanite is an extraordinary collector specimen, combining commanding size with breathtaking color, exceptional transparency, and an imposing crystal presence. Rich cobalt blue melts into royal violet as the crystal turns, revealing the mesmerizing pleochroism that has made Merelani Tanzanite legendary among the world’s finest mineral collectors.

Every face is alive with glassy brilliance, while intricate internal growth features tell the story of a crystal that formed deep beneath the Earth millions of years ago. The beautifully balanced twin termination only adds to its sculptural beauty, making this a specimen that captivates from every angle.

Large, natural, unheated Tanzanites of this caliber have become increasingly scarce, and examples with this combination of size, aesthetics, and presence rarely become available.
