Hair ball.  That is what first came to mind when I saw this specimen.  The fine filliform Millerite crystals are probably 1-2cm long and are thickly matted and stick up to 2cm on Quartz matrix that's light grey to white color makes a great contrast to the Millerite's unreal silvery-gold tones. 

Notice the specimen is glued to a piece of styrofoam that will fit in a plastic box to be aid in shipping.
