Every stone has a story. Maybe it is how it was formed or why it has a specific shape or color. Sometimes a rock tells a story that is sentimental. Do you remember the day you found a rock or perhaps someone gave one to you as a gift? Some stones have ancient fables or myths passed down for hundreds of years attached to them. Almost everyone owns a few rocks that are special to them in some way. PLS member Janie Duncan will be our featured presenter as she discusses stones and the stories they tell.

This program meeting takes place on Tuesday, April 16, 2024 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!

Meteorites Subject of March 19 Program Meeting with Dr. Nick Gessler

Pasadena Lapidary Society’s March 19, 2024 Program Meeting will feature Dr. Nicholas Gessler who will present his Meteorite program. In 2002 Dr. Gessler was honored by the designation of Mainbelt Asteroid “113355 Gessler.” 15 years later, at Duke’s Kunshan,
China campus, he hosted ‘Meteorites China’, the first international conference and exhibition of meteoritics in that country. That was emulated in 2018 by a similar conference in Jilin, China. He has discovered 13 named meteorites in California and Nevada and recovered over 1,400 fragments. Dr. Gessler continues to build a comprehensive private teaching collection, and has recently been involved in documenting the newly discovered ninth largest meteorite on Earth, named EL ALI, from Somalia. It weighs in at 15.15 tonnes and is characterized as a “IA iron.” Most likely no other meteorite has been so intimately connected with the life and fate of so many people as ‘EL ALI.” Although the meteorite is now for sale in China, with the help of colleagues at Almaas University of Mogadishu, 16 videos of it are being analyzed and there is a plan to do exploratory archaeology of its impact site near the Ethiopian border. https://people..duke.edu/”ng46/EL-Ali

PLS member Chris Kyte will provide this month’s Rock of the Month talk about Elestial, also known as Window Quartz, with a specific pattern of terminations that flow throughout the face and body of the crystal.

PLS member Nancy Robb will continue her talk on PLS’ history, this being our 75th Anniversary year. The program meeting takes place at 7:00 p.m. in the Fellowship Hall of The Santa Anita Church, 226 W. Colorado Blvd., Arcadia, CA 91007, on Tuesday, March 19, 2024. Come join us! Doors open at 6:30, admission is free; open to the public. Enjoy refreshments while checking out the display table; bring a rock specimen you’d like identified. Buy a raffle ticket for a few bucks and try your luck at winning a cool rock specimen, slab, or otherwise. We hope to see you there!

Spotlight on Tumbling (Rocks, That is) for February 20th Program Meeting

Pasadena Lapidary Society (PLS) members provide this month’s program at 7:00 p.m. , Tuesday, February 20, 2024 — FIRESIDE ROOM (not Fellowship Hall) of the Santa Anita Church

Rock tumbling is the process of polishing rocks and minerals in a rock tumbler. This involves adding stones or minerals to the rock tumbler along with some abrasives, such as grit, fillers, and water. Phil Lahr will give a presentation on tumbling, discussing the basics – machines, grits, and processes involved. He will also have samples of rock polishing at various stages so you can see and feel the difference from one stage to the next. This is a great educational program for new rockhounds, and a refresher for older ones.

As part of our observance of PLS’ 75th Anniversary this year, Nancy Robb plans to continue her talk on PLS’ history.

Our Rock of the Month talk for February will be presented by Sue Pang as she discusses this month’s birthstone, Amethyst.

This program meeting takes place on Tuesday, January 20, 2024, at 7:00 p.m. in the (**DIFFERENT ROOM, SAME ADDRESS**) FIRESIDE ROOM of The Santa Anita Church, 226 W. Colorado Blvd., Arcadia, CA 91007. Come join us! Doors open at 6:30, admission is free; open to the public. Enjoy refreshments while checking out the display table; bring a rock specimen you’d like identified. We hope to see you there!

QUARTZSITE Here We Come!


Pasadena Lapidary Society members will once again be joining the ranks of rockhounds and lapidarists across the nation – and beyond – in an annual sojourn to our ‘mecca’ of rocks – Quartzsite, Arizona. While this isn’t a fieldtrip that requires a rock hammer, shovel or other tools, it’s a great opportunity to see what wonderful gems and minerals exist in our world – all in one place. There are several gem and mineral shows which are held between December and late February in this town, which swells to over a million visitors in the month of January from a paltry 3,714 +/- residents the rest of the year. One of our favorite shows to check out is the QIA Pow Wow, which takes place from January 17 – 21, 2024, with free admission and free parking and way more than a day’s worth of treasures to see. It’s like a giant open air swap meet held under the beautiful blue sky with giant puffy white clouds floating overhead – which sometimes open up with a quick light rain or a heavy shower – then dissipates as quickly as it starts. Quartzsite is just 18 miles east of the California border, along Interstate 10. One can make it a full day trip, or if you’re able to secure lodging in Quartzsite, AZ or Blythe, CA, turn your visit into more than one day so you can visit the other shows taking place as well, such as Tyson Wells or Desert Gardens. If you prefer to take an RV and camp, there’s plenty of open space just on the outskirts of town. How to get there? Take I-10 East until you get to Quartzsite, about a four hour drive from Pasadena when traffic isn’t bad. We often make a quick stop at Chiriaco Summit either on the way to or from AZ, where one can fuel up and stop for a bite or snacks.

And the rockhound fun doesn’t stop with Quartzsite… read further about the big Tucson Show (the 2023 event is the subject of our January 16 Program Meeting) coming February 8-11, 2024.

January 2024 Program Meeting: TGMS – Not Your Typical Rock Show

The Tucson Gem and Mineral Society knows how to put on a great show.  This society was the first to bring together the hobby enthusiast, the curator/professionals and the general public for this annual four day event. After 68 years, it is the largest, oldest and most prestigious gem and mineral show in the world.  The 2023 show theme was “Silica, Agates & Opal & Quartz, Oh My!”

The 2024 show is slated for February 8-11, 2024. Located at the Tucson Convention Center, attendees will find approximately 250 dealers selling a variety of minerals, fossils, jewelry, and lapidary.  Throughout the show there are lectures and symposiums.  Jaw-dropping world class exhibits from private collections, major universities and museums are on display.  Other exhibit cases,  (both competitive and non-competitive) round out this mix.

For Pasadena Lapidary Society’s Tuesday, January 16, 2024 Program Meeting, our friend Mary Pat Weber will provide us with a visual treat of the highlights of the 2023 Tucson show, and why it rocks!

Rose Quartz and Garnet will be the topics of January’s Rock of the Month talk, provided by PLS Vice President Barna Laszlo.

This program meeting is at 7:00 p.m. at Fellowship Hall of The Santa Anita Church, 226 W. Colorado Blvd., Arcadia, CA 91007. Come to learn and make new friends; open to the public, free admission.

Amethyst Deposits of Thunder Bay, Ontario Subject of October 17th Program Meeting

The largest commercial deposits of amethyst in North America occur near the Canadian border in Southern Ontario.  Unlike the more common Brazilian amethyst, this material is unique due to inclusions of red hematite in the outermost layers of the crystals. Our guest speaker for October, Dick Weber, first visited these deposits in the 1970s while studying for his graduate degree in Geology at the University of Minnesota, Duluth. 

Geologists Dick and Mary Pat Weber have returned to these deposits several times over the years and on two recent visits were given special access to the workings of the deposit by the mine owners.  As part of this presentation they will display some of this highly prized amethyst from their personal collections. 

This program meeting takes place at 7:00 p.m. in the Fellowship Hall of The Santa Anita Church, 226 W. Colorado Blvd., Arcadia, CA 91007, on Tuesday, October 17, 2023.

Come join us! Doors open at 6:30, admission is free; open to the public. Enjoy refreshments while checking out the display table; bring a rock specimen you’d like identified. Buy a raffle ticket for a few bucks and try your luck at winning a cool rock specimen, slab, or otherwise. We hope to see you there!

April 18 Program Meeting Focuses on Rock Collecting in the Mojave Trails National Monument

7:00 p.m., Tuesday, April 18, 2023

What do the Cady Mountains and the Marble Mountain Fossil Beds have in common? These are sample sites Pasadena Lapidary Society (PLS) members and other rockhounds visit to collect rocks including but not limited to chalcedony and agates. The aforementioned sites are also an example of places within the boundaries of the Mojave Trails National Monument (MTNM) in San Bernardino County, California.  PLS members have visited public lands and collected rocks since our Society’s establishment in 1946, while the MTNM was created in February 2016 under the Obama Administration. Some national monuments have banned rockhounding or removed access to rockhounding areas. Currently, rockhounding at the MTNM is still allowed while the Bureau of Land Management (BLM) develops the monument’s management plan. As rockhounds, we need to continue to have road access to collection sites and be able to collect rocks within the MTNM. Gregor Losson, our gem and mineral collecting representative on the MTNM Subgroup of the Desert Advisory Committee (DAC), will be the guest speaker for our April program meeting. Having recently attended the BLM California Desert District Advisory Council meeting, he will illustrate what’s happening and what we need to do to continue enjoying future access to the MTNM.

The April Rock of the Month presentation will be about a junior member’s rock hunting experience. Daniel Nishimura is a PLS junior member. He is eight years old and has been rock hounding since he learned how to walk.

This important and informative program meeting takes place at 7:00 p.m. in the Fellowship Hall of The Santa Anita Church, 226 W. Colorado Blvd., Arcadia, CA 91007. 

Join us to learn more about the future of rockhounding in one of our favorite locales. Admission is free; open to the public. Enjoy refreshments while checking out the display table; bring a rock specimen you’d like identified. Hope to see you there!

Mount Baldy Lapis Lazuli Featured for March 21st Program Meeting, 7:00 p.m.

Pasadena Lapidary Society member Paolo Sanchez will discuss the elusive Lapis Lazuli from Mount Baldy (aka ‘Old Baldy’ or Mount San Antonio) for our March program meeting. Paolo will cover the science behind lapis, its significance to lapidary, and his adventures in search of one of the only lapis mines in North America. He has been an active member of the Pasadena Lapidary Society since 2011, yet his passions for geology and rockhounding stem from kindergarten. He has written numerous award-winning articles on minerals and has been a guest speaker for various California Federation of Mineralogical Societies (CFMS) programs across California. He has received his bachelors in Geology and Geophysics from UC Berkeley and is now pursuing a PhD in geochemistry studying mineralogy and petrology at Caltech.

The March Rock of the Month presentation will be on Septarian Nodules and provided by PLS member Sue Dekany.

This program meeting takes place on Tuesday, March 21, 2023, at 7:00 p.m. in the Fellowship Hall of The Santa Anita Church, 226 W. Colorado Blvd., Arcadia, CA 91007.

Come join us! Doors open at 6:30, admission is free; open to the public. Enjoy refreshments while checking out the display table; bring a rock specimen you’d like identified. We hope to see you there!

Who’s Going to Quartzsite This Month?

Members of Pasadena Lapidary Society, along with most serious rockhounds, wait anxiously all year to make the 3-1/2 hour trek to Quartzsite, AZ in January. Some stay there into February, camping nearby in order to go rockhounding at their leisure, and others check in to the few motels in town or travel the 22 miles back/forth to Blythe, CA for lodging.

Some sizable chunks of beautiful Lapis Lazuli, at vendor booth of a past year’s QIA PowWow in Quartzsite.

One of the biggest draws in Quartzsite is the QIA POWWOW, always held the third week in January. This year the POWWOW runs from January 18-22. If you’ve never been, the POWWOW is like a huge swap meet focused on gems, minerals, rocks and everything related. Admission is free and so is parking.

Other rocks shows taking place in Quartzsite during this time are Desert Gardens and Tyson Wells. Check out the calendar of events from the City of Quartzsite website: http://www.quartzsitecalendar.com/

Self-professed as “The Rock Capital of the World”, Quartzsite is a town in La Paz County of +/- 2,000 inhabitants that swells to a couple of million in January and February each year. Situated 125 miles west of Phoenix at the junction of Interstate 10 and U.S. Highway 95, it enjoys a close association with the Colorado River, just 18 miles to the west.
