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, relatively sharp, deep emerald green color, prismatic crystal of Vivianite which is 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. I believe it’s at least 40 years old, and could date back further. Great condition overall, and how often does one see such attractive association specimens from this locality?
Locality: Siglo XX Mine (Siglo Veinte Mine), Llallagua, Bustillo Province, Potosi Department, Bolivia
Specimen Size: 2.4 x 2.4 x 1.3 cm (thumbnail)
