Stunning cluster of bi-colored Tanzanite crystals. The crystals are gem quality and complete with purple/blue body color and yellow terminations. Clusters are much less common than single crystals and this one presents superbly with two major diverging crystals. Additionally there are smaller crystals and some attached Graphite at the base that give a slight 'matrix' visual effect. Highly aesthetic and undamaged Tanzanite specimen. Weighs 17.83 grams.
