In the early 1980's this mine produced some of the largest and most spectacular Vivianite specimens in Bolivian history. There were plates of crystals just pouring out of the mine for a brief period of time. Then, the mine manager decided that the miners were too distracted collecting Vivianite and not attending to their duties underground, so he decided to blow up the entire section of the mine where the Vivianite was being collected, thus greatly limiting the number of specimens that would make their way to the market. This piece is one of the last specimens to come out of the Morococala during the "Vivianite Boom." It hosts a semi-lustrous, sharp, prismatic deep green crystal of Vivainite measuring 2.3 cm long on iridescent Pyrite on matrix. Ex. Richard Kosnar Collection.
