Fluorite penetration twin, 17 mm group. Icositetrahedron, dodecahedron and cube faces visible. Smoky Hawk Mine, Colorado, USA.

This penetration twin differs from the other complex twins shown in this gallery in that it lacks the enlarged octahedral faces and flattened morphology of the twins from Erongo, Naica and Chumar Bakhoor.
