About Our Society

The Mineral & Gem Society of Castro Valley is a non-profit educational corporation. All members that run this club are volunteers and are not paid. As a member you are expected to learn how to cut a calibrated cabochon (polished gemstone) once you join before learning other lapidary skills. When you learn how to cut a cabochon, you will learn how to use some of the shops equipment. We have professional volunteer instructors to assist you in this process every step of the way so you are not alone.

Monday Nights 7 - 9 p.m. are reserved for beginners so you have the shop all to yourselves to work and learn with instructors. Please make an appointment for your first instruction with the shop manager (see application). Appointments thereafter are made with the instructor.

Below is an example of the work of just one man's idle hands, and a few fossils he bought and was proud enough of to show.

This is an image of the steps it takes to take a slab of lapidary quailty rock and create your cabochon. Your instructor will show how to cab every step of the way!

When you attend our shop clean ups, tailgates and other yearly socials, you will meet other members that can share helpful information on different lapidary arts. You will also have the opportunity to pick up some rock to work on at really good prices.
