A novelty at Tucson 2015. Fibrous Brochantite is very well known at the Milpillas mine but this sample has aggregates of elongated idiomorphic crystals, one of them clearly isolated and doubly terminated, with very well defined faces and edges and chisel like terminations. In our opinion, the world's best for the species for their definition, crystal size, as well as their color and luster and, in general, very high quality.
