Vivianite with Childrenite, Siderite and Paravauxite

A classic association specimen from one of the most well-known mines in Bolivia. Subscribers to the Mineralogical Record know that an entire issue was dedicated to this unique and historic locality. This piece features a wonderful, very sharp, lustrous, deep emerald green color, “sword”-shaped prismatic crystal of Vivianite which is associated with beautifully contrasting golden Siderite and Childrenite aggregates, and rare light green Paravauxite crystals plus minor Pyrite on matrix. The piece looks like it’s from the famous Contacto vein where some of the most important phosphate specimens were found at Siglo XX. This is a historic specimen that was collected in the 1940s when the Siglo XX Mine was booming with new and exciting phosphates! Specimen # BOL711B132
