We Love Rocks

All members of CC M&G; have one thing in common; we love rocks: rocks, stones, agates, jasper, even granite, rhyolite, and andesite.

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…
