I actually consider this to be reasonably significant, as far as pieces from this mine go. Japan law twins from Huanzala are unheard of-- this mine has produced literally thousands of tons of specimens over the last 40+ years, though Japan Law twins are virtually unknown from there. I certainly haven't seen any, and my (much more experienced) middle aged friend in Peru who has been specializing in Huanzala material since his early teens had never seen them before either. This was the best of 3 pieces I was able to get-- the twin is clearly positioned front and center above the pyrite. The pyrite is contacted on the left side, but I actually think it improves the piece in a rather humorous way: it looks like a bunny now.
