Pasadena Lapidary Society’s Tuesday, March 16 program meeting will feature geologists Dick and Mary Pat Weber, whose presentation will focus on the geological wonder of New Zealand. From volcanoes to glaciers, caves and fjords, finding so much variety of terrain in such a small geographical area would be impossible anywhere else on Earth.

The Webers are exploration geologists who spent a month in 2007 visiting every corner of this tiny island nation; they have worked and travelled extensively in North America, Australia and New Zealand.

Focus on Ametrine for Tuesday, February 16th

Join us for our next virtual general meeting on Tuesday, February 16th. We will be joined by our friend, Professor George R. Rossman. Professor Rossman will highlight the troubled history of Ametrine. Specifically, he will discuss the controversy that developed about ametrine early on, and his personal experience traveling to Brazil amethyst mines, the Bolivia ametrine mine, and Russia where synthetic ametrine was produced. RSVP to joenmar1[at]verizon.net for a Zoom meeting link, using ‘AMETRINE’ in subject line.

The Rock of the Month will be presented by PLS member Phil Lahr, who will discuss “Tumbling through the Pandemic” – a personal journey of rock tumbling triumphs and tragedies during the summer of 2020.

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.

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.

Main Presentation
A Brief History of Beads
by Janie Duncan

PLS member Janie Duncan will present ‘A Brief History of Beads’ at our first program meeting of the New Year.


We hold informative monthly meetings. Our meetings are held in the comfort of the Donald Wright Auditorium of the Pasadena Central Library, 285 E. Walnut Street, Pasadena, California. Comfortable seating, lighting, a stage and audio-visual system allows us to attract quality speakers, provide demonstrations and interesting videos for our members!

Meetings are the third Tuesday of the month. Members and guests arrive between 6 pm and 6:30 pm for refreshments and information exchange. A display table at the back of the room allows our Education Committee and society members to display creations, finds, and the birthstone of the month. It is also a place for members and guests to have unknown minerals identified.

Our meetings begin at 6:30 pm and end at 8:45 pm. They include a business session and a program on a subject relating to our earth science hobby. Refreshments are served at a break between the sessions. The program may include demonstrations, slide shows, videos, auctions, show and sell, or lectures on various subjects.
