About Us

The San Joaquin Valley Lapidary Society is located in Bakersfield, California. We are a group of rock hounds dedicated to the sharing of knowledge about the lapidary arts. We meet weekly for workshops in lapidary, silversmith, and wire wrapping/beading. We were founded in 2005, and are incorporated as a 501 (c) 3. Part of our focus is education, and offer a program for area elementary school 4th and 6th graders that supplements their geology studies.

North Edwards trip

 First  of all my thanks to Gene Stirm for organizing this trip that included several rock clubs from our area. We met at 9 am off Clay Mine Road in the Mojave desert, and were greeted by our host and leader for the day Bill Develeiss an engineer from the Rio Tinto mine in Boron.

Our first stop was at his house. There he explained the geology that surrounded us, explained to us what we could expect to find, and finally showed his wonderful collection of rock, minerals and native American tools that we has found over the years.

Next stop was to look for agate/jasper, riolite,  and possible native tools. It seemed to me that the time went all to fast for that part, but our findings were good.

We followed along the dirt roadway to our third stop where we could find the Mojave blue, and here I found a neat piece of chalcedony with crystals showing. Sparkly is always good.


Daughter and I left the group following this stop, and they continued on to a travertine site.  Travertine is a softer stone, and smaller pieces can easily be cut on a trim saw, and polished into beautiful cabs.

Pictured here on the right is our group with Bill talking about how the area was covered in basalt, and later broken up into the pieces that we saw laying everywhere.

Pictured below is Bill showing some of his collection to us at the beginning of the trip.

He has collected moldevites. These are formations created by lightening strikes in the sand, and can be located by the small holes made in the sand when they form.


 The last picture is of his collection of arsenic crystals formed on rock. Also known as cinnabar, it was once used as a tea in China.

We also thank Bill for the modified ski poles that he gave each of us. Very handy for lifting partly buried rock. Saves a lot of bending down.
