A pseudomorph is when one mineral, molecule by molecule, replaces another mineral and keeps the shape of the original mineral. A paramorph is a special kind of pseudomorph. A pseudomorph involving two minerals with an identical composition but different crystal structures. The original mineral forms, but conditions then cause it to be unstable, so it transforms into the other mineral with the same chemical structure while retaining the original crystal shape. Mr. Hardin was in his life the premier collector of Magnet Cove minerals. He may never be surpassed. This estate specimen is from Mr. Hardin's private reserve.
