QUARTZ with PYRITE
Quiruvilca Mine (La Libertad Mine; ASARCO Mine),
Quiruvilca District, Santiago de Chuco Province,
La Libertad Department, Peru
Size: 3" x 2 1/2"
Very pretty crystal group of medium luster quartz with a dusting of small pyrites and one lone sphalerite.
Some crystals missing terminations around the edges (bottom left of 1st & 2nd photos) where it was removed from the pocket - these being easily trimmed out if desired.
