This specimen features a white Kaolinite matrix hosting three overlapping disc-shaped concretions of royal-blue Azurite crystals. The Azurite grew between layers in the Kaolinite and due to extreme pressure the Azurite was compressed and forced to grow laterally, radiating outward, thus frequently forming disc-shaped concretions, and in some instances, near-perfect circles. The color, contrast and symmetry is amazing – a superb and aesthetic specimen in excellent condition.
