Hello and thanks for visiting our web site! Our names are Richard & Cheryl Sittinger, and we have been displaying amazing minerals, tumbled stones, gemstones, and beads at gem & mineral shows since 1995! Our shows are primarily in California where we live, plus the two biggest shows of the year, in Tucson every January/February, and in Denver every September.
Please come and visit us at the show nearest to you and see our amazing selection of treasures from the earth, or contact us if there is something specific you are looking for.
