A marvelous specimen of pyrargyrite decorated with chalcopyrite and calcite from the famous Fresnillo, Zacatecas, Mexico. It shows well shaped pyrargyrite crystals, growing in an attractive cluster. They have a strong metallic luster. Micro crystals of yellow chalcopyrite partially cover the pyrargyrite. White calcite crystals add a nice contrast. In very good condition – some contacts. On acrylic base.
Choice pyrargyrite!
