Fluorapatite crystals, one of them clearly dominant, equant, transparent and very bright, with very well defined faces and edges and implanted on a single doubly terminated Ferberite crystal partially coated by Siderite and Muscovite. Both the color and the crystallographic shape of the Fluorapatite are different than usual for this mine.Minas da Panasqueira, level 2, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro, PortugalFound in 10/2017. Zoned fluorescence long & short UV.
