This is definitely a weird specimen. It features a combination matrix of manganese ore and spongy, pink, rhodochrosite. A crystal of gemmy, colorless gypsum has filled the small open space in a cavity of the matrix. Sitting on the gypsum and partially included within are rhombs of pink rhodochrosite, to 2.0 cm across, that then have a very thin rim of tan siderite enclosing them. The rhodos have been slightly contacted, otherwise this piece would be priced a lot higher. This was part of a well-known specimen in the collection of Gerald Herfurth, a noted Colorado collector.
