Mineralfest is the biannual mineral, fossil, and gem show sponsored by the Pennsylvania Earth Sciences Association (PESA).

Emphasis on minerals: Displayed material typically runs 65 to 75 percent mineral specimens, with additional inventory including fossils, gemstones, and jewelry.

A diverse group of dealers and inventory: At the Mineralfest, dealers of high-end specimens can be found set up elbow-to-elbow with collectors paring down their collections. Show organizers have made an effort to include a large number of vendors (about 60) of widely ranging interests - our vendors currently include species collectors, Pennsylvania locality specialists, fluorescent mineral enthusiasts, fossil experts, and avid field collectors. They bring with them a healthy mixture of classic and contemporary material, including some from old-time collections, and some which was field-collected only a few weeks prior.
