Mineral ZoneTM has sold parts or whole mineral collections. Mineral collections often contain choice mineral specimens no longer being found. These minerals constitute the classic specimens, which provide a baseline for appreciation of new finds. Mineral ZoneTM endeavors to provide the finest minerals, often these pieces can only be found in other collector’s cabinets. Collections handled include:
- Gene Wright – thumbnail collection (2009)
Gene Wright was a Tucson based collector who specialized in Bisbee minerals, and diversified into azurite and calcite, in the thumbnail size.
- Will Estavillo (2008)
Will Estavillo was once curator of the San Diego Natural History Museum, ultimately retiring to Bisbee, Arizona. Mineral ZoneTM handled much of his general collection, including fine tourmaline specimens from San Diego County, California and much azurite from Morenci.
