HUNDREDS of Bolivian minerals specimens all in one update !!

Our most specimen-filled update ever! After weeks of photographing, describing and posting, we are finally ready to announce our giant Bolivian update. Over the last few years I've been culling Bolivian minerals from new finds, old collections, and things I've picked up at shows in the hopes of putting together one great big update. I've even thrown in a few treasures from my personal collection, and my father's personal colleciton. We've posted literally HUNDREDS of specimens spanning TEN PAGES worth of minerals from Bolivia representing classic localities, contemporary discoveries, unique material, rare minerals, hard-to-find specimens, and the definitive species that made Bolivia a hot bed for minerals for centuries. The VAST majority of the pieces listed are priced BELOW $1000, making for a lot of affordable, attractive pieces to add to your collection. It's safe to say that there is no better source online for Bolivian minerals than our website, and this update is just the beginning. We still have hundreds more good Bolivian pieces to post, so enjoy looking at some of our favorite minerals in the world, and stay tuned for more!
