“An aggregate of white bladed crystals of yeomanite along with a small, upstanding aggregate of yeomanite sitting on a bed of colourless calcite crystals that, in turn, sit on an earthy black manganese oxide matrix. A second, much smaller aggregate shows a divergent spray of yeomanite crystals that bridge the gap between a slightly larger aggregate of yeomanite crystals measuring 8x4mm that are partially overgrown by a thin, colourless crust of calcite.
