The El Dorado County Mineral and Gem Society has a NEW website.

The Society was formed to promote the earth sciences and lapidary arts and to encourage the collection and preservation of mineralogical and paleontological specimens. 


These goals are accomplished through activities such as educational meetings, an annual exhibition, exhibits at libraries and at other mineral and gem society events, field trips, lapidary and jewelry arts classes, junior programs,  presentations to local schools and youth organizations, participation at the County Fair.

El Dorado County Mineral and Gem Society does not necessarily endorse the web sites it links to, and it is not responsible for their content or cookies.

Please report any broken links to the Webmaster. Thank you.
