*from the Magma Mine, Globe, Arizona. *80 x 50 x 50 mm overall.
This is a very interesting specimen. There's two generations of quartz. The larger crystals poke up through the drusy quartz crystals. Most of the larger ones have either white or red phantoms. The second generation show hallow casts where some previous mineral has dissolved away (an epimorph). All this on a matrix of pyrite.
