Mineral: Fluorite
Locality: Naica Mine, Torino-Tehuacan Chimney, Naica, Municipio Saucillo, Chihuahua, Mexico
Dimensions: 10 cm on an axis

Description: I got this piece back in 1984 when I was working on my PhD at Santa Eulalia. Got a phone call late at night at the "hotel" (dormitory) to help a dealer friend unload that day's haul from Naica from the trunk of his car. Still have 5 pieces from that trunkload!
