A superb specimen of brochantite crystals from the famous Milpillas Mine, Mexico considered among the best examples for the species. It displays vibrant electric-green color brochantite crystals in a cluster. They are razor sharp and well shaped blade crystals, with a strong luster and some translucence. Many crystals are doubly terminated. The colorfulness of the specimen is tremendous. It shows on both sides. For references see the 2021 issue of The Mineralogical Record vol. 52, # 5. In excellent condition – some small contacts. On acrylic base.

Gorgeous brochantite!
