This is a large and beautiful example of the classic material from Washington, circa the 1950s-1960s. It is an extremely elegant and large specimen. Remarkably, it is nearly pristine (just a few tiny bruises of no import) and furthermore is completely crystallized around the back (where flat crystals seem to have grown upon a contact face where the piece sheared off from its host rock, essentially making it a floater. BETTER In PERSON! This is a significant US mineral specimen and, for the size and elegance, a significant example of the species. And I think it is priced cheaply, myself.
