Among some of our favorite rockhound travel guides are Dick and Mary Pat Weber. For the Tuesday, October 19 presentation, Mary Pat will take us on a Practical Guide to Urban Rockhounding in Tucson.
In a few months dealers, buyers, and collectors will gather together for the largest rockhound event in the world. You will find great bargains relating to all aspects of our hobby offered by vendors from all corners of the globe. If you can’t find it in Tucson, it probably doesn’t exist anywhere. According to Mary Pat, you will run out of money long before you cross off all the items on your wish list.
With over forty shows from which to choose, it can be a bit confusing for the first-timer. Mary Pat will offer practical advice for navigating though the “Tucson experience” to make it both efficient and fun. This program is jammed packed with photo highlights of the biggest club show in the world, including specimens from world class museums such as the Smithsonian and other private collections. If you’ve been thinking about visiting Tucson for the rockhound shows but have yet to, here’s a chance to see what they’re all about.
PLS member Mona Ross will provide October’s Rock of the Month talk on one of the world’s rarest gemstones, Grandidierite.

There’s a controversy brewing over a new and beautiful red transparent gem out of the Democratic Republic of the Congo as well as Tibet or an unspecified location in China. Caltech Professor of Mineralogy George Rossman will discuss his research on this red copper-carrying feldspar at our September program meeting.

Our friends Dick and Mary Pat Weber return to take us on an armchair journey to explore the Geology of California’s National Parks for the main presentation of our Tuesday, August 17 Program Meeting. Some of the finest examples of geologic features in the Western U.S. are on display in the national parks of our beautiful Golden State. They contain a vast array of different land forms and underlying lithologies (rock types) that have been shaped by nature in different environments ranging from cold and wet in the highest mountains, to the extreme heat in the driest of deserts.

We’ve got an exciting feature presentation slated for Tuesday, July 20, 2021 when Gene McDevitt, explorer, entrepreneur, lapidary artist takes us on an armchair trip to Queensland, Australia for Koroit Boulder Opal mining. In addition to Koroit Opal, Gene cuts and wholesales other interesting stones such as Mooka Jasper (Mookaite), Noreena Jasper, Tiger Eye, and Rutilated Quartz, among others.

Join us Tuesday, June 15 for a journey through the deep Earth, with Dr. Krista Sawchuk. The deep Earth, which encompasses the mantle and core, makes up 99% of our planet. Because we can’t physically go to the deep Earth, scientists employ a variety of techniques to learn more about it. Dr. Sawchuk will share what we do know about the deep Earth and how her research on the behavior of minerals at high pressures and temperatures is helping us learn more about the chemistry of the mantle.
Dr. Sawchuk recently graduated from UCLA with a PhD in geochemistry. Her dissertation research focused on the high-pressure behavior and chemical reactions of volatile-bearing minerals in Earth’s mantle. Since graduating, she started a postdoctoral research position at Los Alamos National Lab in New Mexico where she continues her high-pressure research. In her spare time she enjoys mineral collecting and curating her personal mineral collection.

Obsidian is a popular lapidary material to collect and cut. Join Pasadena Lapidary Society at the April general meeting, as lapidary artist Terry Wilson takes us on a virtual trip to Davis Creek and other obsidian collecting locations, updating us on collecting site regulations. Terry will share tips on how to inspect the obsidian in the field and back at home. She will also demonstrate how to line up, slab and cab the material to bring out the best of their unique optical properties, including how to cut a cab exhibiting the cat-eye effect.
The April Rock of the Month will be presented by geologist, Dick Weber. Dick will take us on a tour of a hidden treasure: the Petrified Wood museum of Nebraska.
Join us virtually for the April 20 Tuesday night meeting by RSVPing to joenmar1[at]verizon.net for a Zoom meeting link, using ‘PROGRAM MEETING’ in subject line.
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.
Our program meeting will also feature the Rock of the Month, by PLS member David Lacey, whose presentations are always informative.

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.
Rhodochrosite is so popular with members of Pasadena Lapidary Society that we’re bringing back a two-part video featuring the mining and geology of this lovely mineral. Part One will be presented at the Tuesday, February 18th program meeting. Rhodochrosite is a manganese carbonate mineral that ranges in color from light pink to bright red.
The February Rock of the Month Talk speaker is PLS member Karl Stull. Karl will share some tips and ideas for organizing a co-op display case for Pasadena Lapidary Society’s Annual Gem Show, coming in April.
