Great colors range from magenta to teal. Most of this find tended to be more blues/greens/greys, and specimens with pinks are in the minority. Smaller crystals orbit a 2 cm crystal, and terrific luster really makes this piece stand out. This cluster really highlights how the Chalcopyrite crystal size on the outermost layer effects the luster of the specimen. The contacts on this specimen give a sneak peak into the chalcopyrite cores. This is a terrific, display-worthy specimen! Read up on the scientific analysis of these at https://bit.ly/2MPR6Fi
