Native Bismuth is known from many localities, but the classic nuggets from the Vilaque River in eastern Bolivia are some of the most well known for the species. These nuggests actually are found in Gold placers and weather out of the deposit from glacial erosion. This specimen is a classic example of these nuggets with typical alluvial form and attractive brassy-silver color. A great thumbnail size specimen of this material. Ex. Brian Kosnar.
