Program Meetings

We hold informative monthly meetings online via Zoom on the third Tuesday of the month.  The meetings start at 6:30 p.m. and end around 8:45 p.m.  They include a business session and a program on a subject relating to our earth science hobby. The program may include demonstrations, slide shows, videos, auctions, show and sell, or lectures on various subjects. During the meetings, members and guests can have unknown minerals identified virtually, so long as they provide pictures of the item one week ahead via email to

Prior to the Coronavirus pandemic, our meetings were held in the comfort of the Donald Wright Auditorium of the Pasadena Central Library in Pasadena, California, where attendees enjoyed comfortable seating, lighting, a stage and audio-visual system which allowed us to attract quality speakers, and provide demonstrations and interesting videos for our members.

In March 2020, this library venue was closed to meetings due to a state mandatory directive regarding indoor gatherings to prevent the spread of COVID-19.  Monthly Zoom meetings commenced and can be accessed by way of an invite from the PLS Zoom meeting administrator. Guests interested in attending our monthly Zoom meetings should contact Pasadena Lapidary Society President Ellen Ferrell at to request an invite.

Past programs have included How to Display your Show Case, Petrified Wood, Field Trip First Aid, Mount St. Helens, Rhodochrosite Mining, Thunder Eggs, Larimar, Micro Crystals, Chinese Farmed Pearls, Rock Carving Throughout History, Cultured Rubies, Pink Minerals, Mineral Classification and Identification, Camping Basics and more!

Workshops are Currently Suspended

When our Workshops begin to meet in-person again, we offer a fully stocked lapidary workshop for our members including: Rock saws, full range of cabbing and polishing machines, faceting equipment, project tables and more! (Completion of instruction needed to use some machines.)  In addition, classes are often taught by skilled club members.

Workshops are currently suspended due to California state mandates against indoor gatherings.  They would occur on the second Sunday of each month, with hours from 9 am – 4 pm.

The Pasadena Lapidary Society hosts an annual gem and mineral show during the second weekend of March.

For 2019 the Pasadena Lapidary Society hosted the 80th annual California Federation of Mineralogical Societies Show & Convention from March 8 – 10, 2019 in Pomona, California! Our committee members held monthly meetings to plan and make decisions for this exciting event.

In addition, we try to keep our site updated with information about other local shows. Please visit our events calendar for the latest show updates.

Board Meetings

Board members usually arrive around 6 pm for dinner and conversation before the meeting gets started. The talk is about rock events, vacations, ideas for the newsletter, whatever. PLS members are always welcome to join in.

The President calls the meeting to order around 7 pm. This is a business meeting, and follows certain procedures. The agenda includes approval of minutes, status reports by committee chairmen, Old Business, and New Business. The business items range from routine expenses to policy questions to proposals for new projects. Only Board members may cast votes, and discussion is under the direction of the President. PLS members who visit a meeting and wish to contribute to the discussion will be recognized and given time to speak. A visit to a Board meeting is a good way to learn how the Board works and about Board member responsibilities, especially for those who might be interested in serving on the Board.

Board meetings occur on the 1st Thursday of each month from 6 pm – 9 pm at Matt Denny’s Ale House Restaurant in Arcadia.
