Program Meeting Tuesday, Feb. 17; 7:00 p.m.

Our planned speaker for February had to cancel but fear not — Pasadena Lapidary Society member Bill Walls will give a short talk about field trip findings and we will be watching a movie about a Selenite crystal cave in Mexico. Imagine a cave with massive crystals bigger than telephone poles! Check out this Wikipedia page to get an idea: https://en.wikipedia.org/wiki/Cave_of_the_Crystals

This program meeting takes place on Tuesday, February 17, 2026 at 7:00 p.m. in the Fellowship Hall of The Santa Anita Church, 226 W. Colorado Blvd., Arcadia, CA 91007. Admission is free; open to the public. Enjoy refreshments while checking out the display table. Bring a rock specimen you’d like identified – or maybe you have a special memory attached to one that you can share while you’re at the meeting. Hope to see you there!

Our Tuesday, January 18, 2022 Program Meeting will be held via Zoom. PLS member David Lacy will provide the evening’s presentation as an overview of Crystals and Crystal Forms.  We will look at the differences between geometrical (ideal) crystal forms and some of the crystal habits in nature, where geometric forms meet the real world.  We will check on just what are the characteristics of a crystal, what is a crystal habit, symmetry in crystals, and the seven crystal systems met in nature.  Some mineral specimens will be visually shared to demonstrate real-world crystal habits. Meeting starts at 7:00 p.m. If you’d like to join us, write marcia.pls.emails [at] gmail [dot] com to request a Zoom link.
