We are field collectors with a combined experience of 50+ years. In our hunts for old, forgotten sites we enjoy not only the thrill of discovery, but also the history of the places and people who made them possible.  We specialize in fluorescent minerals for sale.  We offer quality metallic, rare, classic, old time and unusual specimens for purchase. Some of the items we offer come from old collections, some are self collected. On our sites you will find localities not represented elsewhere. We hope to share our joy of mineral collecting and knowledge with you.
