3.9 x 3.0 x 2.7 cm. Aphrosiderite is an ULTRA-RARE non-approved member of the Chlorite Group, 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 lustre. A very old, mostly illegible paper label is glued to the bottom. CLASSIC and OLD material from the Richard Hauck Collection.
