We Love Rocks!

All members of CCM&G have one thing in common; we love rocks: rocks, stones, agates, jasper, even granite, ryholite, and andandesite.

Some of us are gemologists, some are geologists. Many have interests in both the structure of the earth and the cleavage of a crystal. Some are very specialized in a single field. Our members include amateurs, professionals, PhD's, rockhounds, and even scrubby rockhounds. We even have some scrubby PhD rockhounds.

The one thing we all appreciate is the beauty of the earth and the beauty of the earth's bounty. Call it crystallography, rockhounding, geology, or earth science. In a word, we love rocks! It's rockology...

Sharing the Gem

CCM&GS members enjoy a bountiful array of educational classes in the lapidary arts, geology, and mineralogy; educational lectures, and nearly unlimited access to geologic and rockhounding field trips throughout California.

And CCM&GS gives back. CCM&GS has targeted programs for young rockhounders and provides speakers to local schools at every grade level. Educators and students, check the Kid's Corner.
