Ripidolite is a relatively rare variety of clinochlore, a chlorite group species. This old-time cabinet specimen features dark, greenish-gray ripidolite after sharp almandine garnet dodecahedrons set in greenstone matrix from the old Michigamme Iron Mine of Michigan. The pseudomoprhs reach 2.1 cm on this fine specimen. Excellent material from this historic mine. Ex. George Elling Collection.
