Group of lanceolate Muscovite crystals, extremely fine, aggregated in sheaves, with the characteristic pearly grey color and with terminations of a darker tone. At the base of the Muscovite crystals, several Fluorapatite crystals have formed, with well-defined faces and edges, a pale green color, and good luster. The combo is complemented by a multitude of tiny Siderite crystals at the base of the piece which cements the whole together.
