This is a truly outstanding, significant, world class phenakite specimen from the important finds here of the 1940s and early 1950s (the "Pough era" as some call it). It has only recently been sold to me out of a private collection and has some history with it which will come with purchase. I have NEVER seen such a significant Brazilian phenakite for sale, and this blew me away when it turned up. It is complete all around as you can see from the front and back shots, nicely crystallized on both sides. To me, this weird and exotic mineral is much more interesting than just another tourmaline for the price, and far more irreplaceable.
