Hosted by the Oklahoma State Council of Mineralogical Societies, this Spring Rock Swap welcomes everyone to the OSU campus this April. Vendors will have rocks, minerals, fossils, lapidary equipment and finished jewelry for sale or trade. This family-friendly event is free and open to the public. Anyone interested in rocks and minerals and the lapidary hobby is invited to attend. A live auction at 11:30 am, featuring donations from the vendors and other rockhounds, is open to the public. The proceeds go to the OSCMS Scholarship Fund.
