“The Colorful Condor Agates of Argentina”, Subject of September Program Meeting

7:00 p.m., Tuesday, September 16th, 2025

Our main speaker for the September program meeting will be Mary Pat Weber, geologist and mineral collector, who will present “The Colorful Condor Agates of Argentina”. She will present the amazing story of how these agates were discovered, lost, and re-discovered in a remote, inhospitable region high in the foothills of the Andes Mountains. Condor agates are colorful, tightly banded agates and patterned agates found in the mountains near San Rafael, in Mendoza Province, Argentina. This agate has become a popular stone among collectors and jewelry designers. Specimens of these beautiful agates from Mary Pat’s personal collection will be on display at the meeting.

There will also be a short talk at this meeting in the form of a recap of our members’ experiences at Camp Paradise, a CFMS-sponsored lapidary and jewelry camp. As a group, we attended every class offered this year. We learned new things and made beautiful projects. Camp Paradise offers two 1-week sessions each August for members of CFMS affiliated clubs such as Pasadena Lapidary Society. Come learn about this wonderful experience and make your plans for next year.

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.

Admission is free; open to the public. Enjoy refreshments while checking out the display table; bring a rock specimen you’d like identified. See you there!

Pasadena Lapidary Society Members Win Big at Annual CFMS Show

Sue Dekany with her CFMS awards


Pasadena Lapidary Society members Sue Dekany and Sandie & Tony Fender walked away with key awards at the annual CFMS (California Federation of Mineralogical Societies) Show and Convention held this year in Lancaster on May 10-11.

Sue Dekany, PLS Secretary, had been working toward entering a competitive case in late 2024.  Then came the Eaton Fire, and Sue’s accumulated work was trashed.  Out of the ashes, however, Sue thought the remnants would make an interesting educational display.  Boy, was she right!  Over Mother’s Day weekend she set up her Novice-Educational-General Concept-General Audience display showing her rocks that had been cooked in the Eaton Fire, submitted the case competitively in the Novice category of the CFMS show and the result: a Double Win with ‘Best of Show’ and the ‘President’s Award’.  (Sue’s exhibit will be on display again September 20-21 at our annual show in Arcadia.)  Sue’s observations from her rock collection debris: many rocks were massively oxidized (pyrite, some jaspers, onyx and serpentine), every bit of metal lost its protective polish, obsidian fractured in a spiral, but otherwise looked normal, quartz crystals and fluorite turned white and brittle, and amazingly an apatite cabochon survived, looking the same as before the fire.

Sandie and Tony Fender share the CFMS Golden Bear award

PLS members Sandie and Tony Fender were presented with the illustrious Golden Bear Award, given only to recipients in recognition of outstanding service to the CFMS.  Tony and Sandie are both retired educators and lifelong rockhounds.  Over the years they have dedicated much of their time and efforts to holding various positions in the CFMS and are members of several gem and mineral clubs in Southern California.  They’re also avid square dancers! The Pasadena Lapidary Society is beaming with pride over these wins. 

The California Federation of Mineralogical Societies represents over 100 gem and rockhound clubs statewide, as well as a few clubs in Nevada and Arizona.  Visit cfmsinc.org for further information.

Pasadena Lapidary Society Member Awarded Scholarship by CFMS

Pasadena Lapidary Society (PLS) is proud to announce that member Paolo Sanchez of Burbank has been awarded the California Federation of Mineralogical Societies’ (CFMS) Robert O. Deidrich Memorial Fund Scholarship for school year 2020-21.  This award was established some fifty years ago by the late Melba Deidrich in memory of her husband Robert.  The recipient of the $2,000 award must be an Earth Sciences major entering his/her junior or senior year at either UC Berkeley or Stanford University. Pasadena Lapidary Society is one of many member clubs in the CFMS.

As Filipino-Americans, Paolo’s parents Debbie and Ferdie trained and worked hard to establish themselves in the U.S.’s medical industry, and through their dedication and experience—as well as wonderful support from his older brother Joshua and younger sister Danielle—Paolo has been able to obtain a first-generation, U.S.-college education at UC Berkeley. With this he plans to continue his passion in the geosciences, working his way up to a PhD and possibly obtaining a career as a professional researcher.  He is in his third year of double majoring in geology and geophysics and is developing a research project involving the chemistry of molten glasses (tektites) formed during the meteor impact that killed the dinosaurs (a.k.a. the K-Pg Impact) 66 million years ago.

Paolo became interested in Earth Sciences as a kindergartener, developing an affinity for rockhounding through the years by reading geology field books and old textbooks, then applying that knowledge in the domain. He joined PLS as a Junior member at the age of 12 and since then he has given lectures about geology at PLS’ monthly program meetings, led educational rock and mineral identification seminars, and authored/coauthored numerous geological and mineralogical articles in the monthly PLS newsletter Rockhound Ramblings, among numerous invaluable contributions he has made to the Club. As part of Pasadena Lapidary Society’s community outreach, Paolo has taught basic geoscience to local elementary school students, along with providing hands-on teaching techniques with self-collected rock and mineral specimens.

Paolo in the San Gabriel Mountains

Prior to UC Berkeley, Paolo interned at Cal State Northridge for a year, doing research for the Geological Sciences Department.  At present he is a Research Assistant at both the Berkeley Geochronology Center and at the UC Berkeley Earth and Planetary Sciences Dept.  Paolo is also an editor and contributor to the popular non-commercial online mineralogical database mindat.org.

Along with his family, Pasadena Lapidary Society shares great pride in Paolo’s accomplishments, congratulates him at winning this prestigious award, and wishes him much success in his future endeavors.
