A RARE and showy specimen of a vug richly lined with lustrous, deep blue, dipyramidal quartz crystals colored by aerinite inclusions from near Malaga, Spain. Aerinite is a RARE silicate, found worldwide almost exclusively in Spain. A well-written article on this find is found in the Mineralogical Record, Volume 27, Number 2, 1996. This is quite good for the material.
