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 stages you will go through to make your first cabochon. First you start out with a slice of rock, draw an oval on it and start grinding the stone away. You will take the stone through many differnt steps to achieve a nicely polished and domed stone.

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!

Volunteer & Become Involved

Members can keep up with current events within the club by:
· Visiting this website often
· Reading their monthly Petrographs (except July & August)
· Attending general meetings

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.

Library

Members also have access to a very complete library with informational, research and technique books and videotapes/DVD's. These are all available for check out. If a book is late we charge overdue fees, so please
return or renew a book to borrow it longer. We also subscribe to several professional journals that must be
used on site. Older copies are available for check out. This is surely one invaluable resource you do not
want to miss out on!

The Mineral & Gem Society of Castro Valley members volunteer their time to give educational talks to kids of all ages in local classrooms. We are always looking for new members that are free in the daytime to help with this educational and fun experience. Our society also donates two scholarships every year to two Cal State University, East Bay (Hayward) geology major students. Every aspect of our club focuses on the education of the lapidary arts, geology and mineralogy.
