JC40W0: Colorless, transparent and bright crystal formed by the clearly dominant faces of the dodecahedron, a very infrequent occurrence on Fluorite crystals, with minor faces of the cube and octahedron. It is on matrix, with Calcite and twinned crystals of Galena on Calcite. Neither the photos nor the 3D imagegive a perfect vision of the crystal, since it is extraordinarily transparent and very luminous.
