One of the nicer clusters of quartz crystals that I've seen from this old quartz mining operations. It was last mined in the 1940's for quartz crystals for electronic purposes. This piece has many nicely terminated, clear quartz crystals pointing more or less vertically. The crystals are clear, colourless quartz crystals, some with auxiliary faces in addition to prism and rhomb faces. If view from the back, the crystals are frosted and packed with small quartz crystals and fragments. Looks great!
