Very aesthetic specimen formed by a group of hyaline and translucent quartz crystals interpenetrated and with recrystallized bases. They are accompanied by various prismatic crystals of fluorapatite showing hexagonal shapes truncated by the basal pinacoids and indications of the dipyramid faces. They are translucent, defined and with striated prism faces and show a delicate violet zoning, more intense in the central part of them. Likewise, they are accompanied by small crystals of muscovite and arsenopyrite along with some siderite. A display piece from this classic Portuguese mine.
