Aphrosiderite is an obsolete name for a chlorite group member (originally described from a mine in Germany). This is a pristine, super-sharp aphrosiderite pseudomorph after a large garnet crystal from the iron mines of Marquette County, Michigan (probably 1950s or earlier). The black crystal has textbook dodecahedral garnet crystal habit and moderate luster. A very old, mostly illegible paper label is glued to the bottom. CLASSIC and OLD material from the Richard Hauck Collection.
