The last piece I have from this extremely rare find of multiple pseudomorphs from the locality.Even double is rare and on those pieces one case azurite altering malachite and/or altering gypsum,which alters limonite and vise versa,altering goethtite which alters calcite.The phaenomenon is unique and the piece is even beautiful,with great colors and overall aesthetics!No damage!
