Numerous purple Herderite crystals to over 1cm on Muscovite that has partially replaced a large Feldspar crystal. The larger crystals are obvious but there are also many (50?) smaller crystals all among the mica. The Feldspar is still present at the core and visible on the bottom with the outer layer replaced to mica. From a friend's personal collection who purchased it in Brazil in the 1970s, size 8 x 5.5 x 4.5 cm.
