Superb, razor-sharp, and lustrous epitaxial growth of Wodginite over Cassiterite. Aesthetic, rare, and world-class. This is an important specimen from a small find, of the early 1980's, that really surprised people. These crystals consists mainly of wodginite that has grown epitaxially over a decaying core of cassiterite that is now barely present at all. The wodginite from this find is superb - unusually lustrous and sharp compared oto the mineral from other localities. These are very hard to come by. I am told that the pocket was only the size of a basketball and the find limited to some dozens of specimens. This one, at about an inch, is one of the larger pieces and is quite significant; not surprising given Marilyn's proximity to Richard Gaines who analyzed them, and handled most of them at the time.
