These Azurite–Malachite–Chrysocolla specimens feature a striking mix of copper secondary minerals. The deep blue of azurite [Cu₃(CO₃)₂(OH)₂] pairs beautifully with malachite’s vivid green [Cu₂(CO₃)(OH)₂], while turquoise chrysocolla [(Cu,Al)₂H₂Si₂O₅(OH)₄·nH₂O] adds a vibrant accent. These minerals form together in the oxidation zones of copper deposits, creating colorful combinations highly prized by collectors. With Mohs hardness values ranging from 2–4 and rich natural patterns, each specimen is a unique representation of copper’s mineral diversity.
