A beautiful Pyrrhotite Sphalerite Cluster also featuring small quartz crystals, on matrix. The Pyrrhotite crystals are medium sized. Looks like an interesting Sphalerite Crystal in the crevice of the matrix. This is a great piece to show the different shapes of the two minerals, which are often found together. A very nice piece from a collectible location. Pyrrhotite crystals are rare and hard to come by.
