Rock&Gem Magazine Description:

Rock & Gem has been the leading magazine for the lapidary and mineral hobbyist. Not a trade journal and not a scientific dissertation, it speaks to the average rock hound, providing just the right blend of entertainment and satisfying information. Armchair hobbyists and diehard diggers alike will find something to enjoy in each issue.

Lifetime hobbyist and Carnegie Award winner Bob Jones heads up a group of experienced and knowledgeable contributors. Bob’s light - hearted style brings readability to in-depth articles on minerals, classic deposits, and collecting trends. His Frugal Collector series helps collectors learn to identify mineral bargains, and his affiliation with the Tucson Gem & Mineral Society provides a behind-the-scenes look at the year’s biggest and best mineral show and sneak previews of the show’s theme and featured exhibits.
