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 few wonderful, relatively sharp, semi-lustrous, deep blue green color, prismatic crystals of Vivianite which are associated with beautifully contrasting golden Childrenite aggregates, and rare light green Paravauxite crystals on the back/reverse side of the specimen. 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! Great condition overall, and how often does one see such attractive association specimens from this locality?
