FLUOAPATITE, PYRITE, SIDERITE, MUSCOVITE

Very curious specimen that shows two types of fluorapatite crystals. One of them very aerial, with prismatic faces and dipyramidal faces of various orders. The other, making functions as a matrix, with well developed dipyramidal faces, really complex... A crystallographic pleasure. Accompanied by brilliant samll pyrite and some muscovite. The main crystal is: 4 x 3,6 x 2,7 cm. Fluorescence UVC & UVA.
