Paligorskite with Calcite, Metaline Falls, Washington, ex. Louis Lafayette Collection #359, Small Cabinet 2.7 x 6.0 x 11.0, $125. Online 9/22.
This is as much of a calcite specimen as a paligorskite. Very sharp discoidal calcite with bright white paligorskite and no point of attachment; complete floater. On a personal note, when I was a kid, we used to call the paligorskite "mountain leather". A western classic. In top condition.
