This specimen features a twinned, bi-terminated montebrasite crystal measuring about 3 x 3 cm, perched in matrix of lepidolite. The crystallized lepidolite is in long tube-like forms. Most unusual matrix and a rare association as far as I have seen. The montebrasite is complete, although partially etched, and sticks up like a breaching whale tail from the matrix for a sharp contrast. The specimen, as a bonus, is rich in globular aggregates of the rare species zanazziite, clustered in and amongst the lepidolite and albite matrix.
