Thunder Bay Red Cap Amethyst chunk

This beautiful 2.1 kg chunk of quartz and amethyst heavily features red cap amethyst (also called Berry Amethyst). It also contains some tin pockets of druzy quartz as well as one pocket that holds what might be amazonite (it's difficult to tell for sure without damaging the piece) and what is definitely a tiny piece of chalcopyrite. We personally picked this piece up at Blue Point mine in Thunder Bay, Ontario.
