These stibnites all have little or not matrix or other associated minerals. They are very nice, bright clusters of intergrown crystals with interesting sculptural shapes. The Quiruvilca ("sacred tooth") Mine, also known as the Asarco Mine or La Libertad Mine, is named after a nearby volcanic neck.

CR 1329: Stibnite, Quiruvilca Mine, Peru: 3.8 cm x 4.6 cm x 3.4 cm, 60.9 grams. $19. Nice interpenetrating crystal cluster.
CR 1563: Quartz, Pasto Bueno, Peru: 8.2 cm x 4.0 cm x 3.7 cm, 107 grams. $35. A nice small cabinet combo with abundant sulfides. Contacted on the bottom and back. I considered sawing off the base of this and can do that if you would prefer it that way to make it stand better and get rid of a little of the excess quartz at the base.
CR 1331: Stibnite, Quiruvilca Mine, Peru: 7.1 cm x 3.1 cm x 1.4 cm, 28.5 grams. $14. A nice elongate cluster, displays well from either side.
CR 1337: Stibnite, Quiruvilca Mine, Peru: 6.3 cm x 3.3 cm x 2.6 cm, 69 grams. $24. Interpenetrating sprays of crystals in a nice small cabinet piece.
CR 1335: Stibnite, Quiruvilca Mine, Peru: 7.0 cm x 4.3 cm x 3.4 cm, 97 grams. $45. Excellent small cabinet specimen with lots of open space between the individual stibnite crystals.
CR 1336: Stibnite, Quiruvilca Mine, Peru: 6.2 cm x 3.7 cm x 1.7 cm, 40.9 grams. $17. A nice fan shaped spray of sharp stibnite crystals.
CR 1330: Stibnite, Quiruvilca Mine, Peru: 3.6x cm x 3.8 cm x 3.7 cm, 74 grams. $19. A nice solid group of interpenetrating sprays with a minor bit of attached matrix with small quartz crystals.
CR 1338: Stibnite, Quiruvilca Mine, Peru: 5.5 cm x 3.4 cm x 1.1 cm, 27.7 grams. $14. Very nice fan shaped cluster (large miniature/small cabinet). Sharp crystals.
CR 1339: Stibnite, Quiruvilca Mine, Peru: 6.0 cm x 2.5 cm x 3.4 cm, 35 grams. $39. This small cabinet piece is probably the most aesthetic of the lot. Displays very nicely with a little help.
