Description/Interesting Notes:
 
A classic example of pyrrhotite from Mexico!!!  This specimen consists of a large single crystal of pyrrhotite in association with a sharp complex 
crystal of sphalerite!!!  The pyrrhotite crystal is sharply defined and actually appears to be partially altered to limonite!!!  The pyrrhotite crystal 
also has a few scattered crystals of arsenopyrite embedded in its surface!!!  The sphalerite crystal is nearly black in color, sharp, and highly lustrous!!!  The 
pics hardly do it justice!!!  
Good luck and be sure to check out my other exciting mineral auctions on ebay!!!
