Typically the Silver specimens from Bolivia are somewhat "flat" and boring, but this piece is amazingly aesthetic for a Bolivian Silver. It is a fine, decent-sized (for this mine) group of crystalline Silver forming a very attractive specimen. This is a great miniature specimen from a classic Bolivian locality, but please note that this specimen is FRAGILE, so it must be handled carefully. The mine at Porco is THE oldest and most significant Silver mine in Bolivia, and obtaining specimens is next to impossible because miners rarely bring out anything for sale, as the mine is a large commercial production, and virtually everything goes into the crusher. Most everything that evades the crusher is usually taken out of Bolivia by a geologist who has an "in" at the mine, or sometimes some brave miners risk losing their jobs by sneaking out a handful of specimens to raise a little extra money to feed their families. It is very difficult to obtain any good Silvers from Porco. Ex. Brian Kosnar.
