Since 1971, Rock & Gem has been the leading magazine for lapidary and mineral hobbyists. Not a trade journal or a scientific dissertation, it speaks to the average rockhound, providing the right blend of entertainment and information. Armchair hobbyists and diehard diggers will find something to enjoy in each issue.
