From an incredible recent find, this amazingly iridescent and colorful goethite, which formed stalactitically, has botryoidal form on the surface which reflects its pink, red, gold, orange and other colors in every direction. Goethite is usually such a boring mineral, but now and then, as here, it can be incredibly bright and lustrous. An uncommonly colorful and beautiful form of a common mineral, here in a showy, large size.
