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.

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.

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.

North Cadys Fieldtrip; Nov. 27-29, 2020

PLS Members visited one of our favorite spots for gemstones in the North Cady Mountains, about three hours northeast of Pasadena, over Thanksgiving weekend.

The Cady Mountains have produced more gemstones than almost any other Southern California location and we explored the northern part of the range, looking for jasper, agate, fluorite, calcite, and amethyst in places where few rock hounds go. You can join us in the Cadys sometime in the future, by becoming a member of Pasadena Lapidary Society. Check out the photos below to see some of our finds.
