Welcome to
The Uncarved Block

Here you will find all of the wonderful minerals that you
have come to expect from seeing us at major mineral
shows around the world.

Browse our online store, see us at one of our upcoming
shows or stop by our gallery and rock shop at 110 North
Main Street in Sebastopol, California.

We have on display one of the largest collections and
the greatest variety of minerals and crystals in the
San Francisco Bay Area!!!

Currently our normal operating hours are 10 AM until 7 PM
(or 7:30 or 8 or whenever our customers leave), Tuesday
through Sunday. We are working toward being open 7 days
a week. You can reach us by telephone at 707-829-7625
during business hours. Or, if after hours, please email and we will get back in touch with you right away.

We may already have what you want, but if we do not have it on hand we can almost always find it somewhere in the world. Please use our email or simply call us at our store for any special or unique items you may wish to acquire.

We also have many wholesale customers. We buy many items in bulk directly from the mines and international jobbers so if you are a reseller please contact us.

We hope that you enjoy our website, and we look forward to serving you.
