One of the longest and best-preserved examples of these famous pseudos that I have seen, this is very dramatic in person! The piece is complete all around and 3-dimensional! These occured as floaters in the sand of the White Desert, and erode out over time. French dealer Alain Carion and his son made the long trek out to colelct them several times, but I am told that it is difficult now. The specimen features cube-liek crystals sticking out every which way from a central stalk, and displays equally nicely whether upside-down with a knob on top or this-way-up as marty had it with the more isolated crystals on top. 16.2 x 3.9 x 3.8 cm
