From the classic San Francisco mine in Mexico, this is a beautiful specimen of Wulfenite which hosts several sharp, lustrous, translucent/gemmy, butterscotch color tabular crystals on gossan matrix. The "main" crystal at the top of the piece measures 1.7 cm on edge. The Wulfenite crystals are associated with small yellow botryoidal Mimetite aggregates as well. Ex. Brian Kosnar Collection.
