Geode Presentation and Discussion on Clear Creek Management Area, Topics of May Program Meeting

Tuesday, May 20th, 7:00 p.m.

Pasadena Lapidary Society member Armando Pedroza has been cutting geodes for over 15 years at gem shows and club presentations. In our upcoming May general meeting he will be presenting and demonstrating his geode program. Geodes will be available for purchasing and he will be cutting them for those who wish to see the magic inside. Geode prices range from $10 to $90. The geode program will be outside on the patio.

PLS member Paolo Sanchez will present a program on the Clear Creek Management area in San Benito County, California. It has been a popular spot for geologists, mineralogists and rockhounds alike for over a century. Part of a large geological feature known as the New Idria Serpentine Intrusion, this area is home to various rare and interesting minerals such as demantoid and melanite varieties of andradite garnet, plasma agate, jadeite, uvarovite, zeolites, as well as asbestos and mercury minerals. It is also where twenty new minerals were first discovered, including the California state gemstone, benitoite. With such a bounty of mineralogical wealth, what makes the New Idria Serpentine Intrusion so special? This talk will delve into the underlying geologic history of the area as well as the interesting minerals that make New Idria a unique place in the mineral world.

This program meeting starts at 7:00 p.m. in the 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.

Author Renée Newman to Speak on Diversity of Gems

Tuesday, Nov. 19th at 7:00 p.m.

Renée will provide a PowerPoint presentation that will include gems from California, Oregon, Washington, Arizona, Nevada, and Idaho. It will focus on the most notable ones such as tourmaline, jade, benitoite, sunstone, opal, turquoise, chrysocolla, fire agate and Four Peaks amethyst, and the places where they are mined.

Members of the Pasadena Lapidary Society are fortunate to live near areas with a diversity of gems. For example, the distance from Pasadena to the Oceanview mine in San Diego County is only 105 miles. There you can dig for tourmalines, kunzites, morganites, and aquamarines, and take a jeep tour of Chief Mountain where you can see the currently active mines. Historically that area was important. From 1898 until 1911, it was the world’s largest producer of tourmaline and it is still producing high quality material. Renée’s presentation will also briefly discuss other mining areas in the Western states.

Renée Newman is the author of books that show readers how to visually evaluate the quality of gems. She has written multiple books on gems and jewelry. The books will be available for sale at the meeting for a discounted price. Bring cash or check. For more information about Renée and her books go to www.reneenewman.com. You can connect with her on Instagram @reneenewmangg and Facebook at https://www.facebook.com/ renee.newman.5648/

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, November 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!

PLS Members’ Field Trip ‘Show and Tell’ Experiences Subject of Tuesday, October 15th Program Meeting, 7:00 pm

Location: Fireside Room at the Santa Anita Church

The Pasadena Lapidary Society October General Meeting will be held in the Fireside Room because our regular room is going to be used for election training. As PLS President David Lacy phrased: “the meeting will be very cozy”. It would be difficult to set up a slide show in the Fireside Room or outside depending on the weather, so we will not have an invited speaker in October. Instead, we will feature three of our club members — Sue Dekany, Curtis Kan and Daniel Nishimura — who will give ‘show and tell’ talks about recent
field trips to the Clear Creek, CA area, the Dead Camel Mountains, NV and McDermitt in OR/NV. Daniel’s upcoming speech is going to be about his adventure collecting Wonderstone in the Yellow Mountains near Fallon, NV.

This program meeting takes place on Tuesday, October 15, 2024, at 7:00 p.m. in the 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!

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.

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!

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.
