These two parallel-growth crystals are unusual for their long prismatic crystallography and size (about 5 cm). They fluoresce a vivid yellow- green color and both crystals are doubly terminated. Ex. Peter Zodac (1894-1967) collection. Peter was a well known collector who founded the journal, Rocks & Minerals in 1926. Specimens with his original labels are scarce on the market today. I am told that this is a very old, rare style for willemite from this mine, and it is probably from the early 1900s. Note the startlingly strong, green fluorescence. Ex. Larry Conklin Collection
