Conejo Gem and Mineral club was founded in 1971, and is a member of both the California Federation of Mineralogical Societies and the American Federation of Mineralogical Societies.

NOTE: "Conejo" pronounced 'kon-a-ho (n) is the Spanish word for "rabbit", hence the logo design, and was the name given by the early Spanish explorers in the early 1700's when they came through the valley and noticed the thousands of jack rabbits that lived here, thus designating this area the "Conejo Valley".

The Conejo Gem and Mineral Club (CGMC) is a non-profit organization run by volunteers. The Club promotes and extends the knowledge of minerals, geology, fossils, lapidary arts and associated fields.
