A very aesthetic specimen formed by a large group of silver crystals and filaments, forming spongy and skeletal growths. Good luster and a slightly tan tone. Stresses this specimen by several factors. One is its size and weight (on 40 g. or 1.4 oz.). Another is the abundance of this noble metal and perhaps the most interesting is that it is not an acidified sample. This is a plate obtained from a natural fissure in the host rock, with a lenticular and flattened structure. A very different piece from this classic Catalan locality.
