Diamonds?… In California?… and Just About Everything Else You Might Want to Know About a ‘Girl’s Best Friend’

Tuesday, November 15 Program Meeting, 7:00 p.m.

For our November Program Meeting, we’re delighted that Renée Newman will be our speaker, providing images and information in her presentation on Diamonds that includes, among other things, the most significant discoveries of rough diamond crystals, five basic diamond crystal types and their relative value from highest priced to lowest priced, where to find diamonds in the U.S., and what American diamonds look like in the rough in order to help you spot them while prospecting and rockhounding.

Renée has a book out entitled Diamonds: Their History, Sources, Qualities and Benefits and much of her presentation is reflected in her book.

Renée Newman developed her interest in gems while conducting tours to Asia, South America and the South Pacific. Her passengers wanted information about the gems that were displayed in hotels and stores so she signed up for a colored stone grading course at the Gemological Institute of America (GIA) in order to be able to answer their questions. The teachers there inspired her to complete the GIA colored stones and diamonds program.  

After receiving a graduate gemologist diploma from the GIA, Renee was hired as a gemologist at a diamond wholesale firm in downtown Los Angeles. It provided hands-on experience grading diamonds and selecting colored gems and pearls for their jewelry. Armed with trade experience and gemological credentials, Renée decided to create books that showed readers how to visually evaluate the quality of gems. Her first book, the Diamond Ring Buying Guide, was published in 1989. Since that time, she has written thirteen more books on gems and jewelry, including the Diamond Handbook geared to trade professionals and her new large-format book Diamonds: Their History, Sources, Qualities and Benefits. Information about it is available at http://www.reneenewman.com/diamonds.htm

Renée’s books are used as consumer guides, gemology course textbooks, sales training tools and appraisal references and are listed at www.reneenewman.com/books.htm.  Renée will be selling her books at a discount and autographing them before and after her presentation. Bring cash or a check if you would like to purchase copies of them.

PLS member Curtis Schurer will discuss Jasper for the Rock of the Month presentation. Jasper is an opaque, impure variety of silica, comes in several colors, and is often found in the Mojave Desert.

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. 

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. See you there!

Gem Pegmatites of Southern California Subject of March 15 Virtual Program Meeting with Walt Lombardo

Zoom Meeting starts at 7:00 p.m., Tuesday, March 15, 2022

Walt Lombardo, Owner & Founder of Nevada Mineral & Book Co., located in Orange, Calif.

Southern California is known worldwide for the production of gemstones and mineral specimens from the granite pegmatites in San Diego, Riverside & San Bernardino counties. Some of the more well-known gem minerals are Tourmaline, Garnet, Aquamarine, Morganite, Kunzite, Quartz, Topaz and Lepidolite. Most notable are the Pala and Mesa Grande mining districts, which supplied beautiful tourmalines to the last Dowager Empress of China in the early 1900’s, and continue to produce world-class gems and mineral specimens today. Our program speaker this month is Walt Lombardo, a geologist with over 35 years experience related to mining and mineral exploration. Walt’s talk will include discussion of the regional geology which made these deposits possible, history of mining in Southern California, some of the more important mines, and the gem minerals that they produced.

Meeting starts at 7:00 p.m. If you’d like to join us, write marcia.pls.emails [at] gmail [dot] com to request a Zoom link.

Our Tuesday, January 18, 2022 Program Meeting will be held via Zoom. PLS member David Lacy will provide the evening’s presentation as an overview of Crystals and Crystal Forms.  We will look at the differences between geometrical (ideal) crystal forms and some of the crystal habits in nature, where geometric forms meet the real world.  We will check on just what are the characteristics of a crystal, what is a crystal habit, symmetry in crystals, and the seven crystal systems met in nature.  Some mineral specimens will be visually shared to demonstrate real-world crystal habits. Meeting starts at 7:00 p.m. If you’d like to join us, write marcia.pls.emails [at] gmail [dot] com to request a Zoom link.

DIY ‘Field Trip’ to… Quartzsite, AZ!

QIA PowWow photo credit by Sue Peng

For the month of January, many members of Pasadena Lapidary Society join the ranks of rockhounds and lapidarists across the nation – and beyond – in an annual sojourn to our ‘mecca’ of rocks – Quartzsite, Arizona. While this isn’t a fieldtrip that requires a rock hammer, shovel or other tools, it’s a great opportunity to see what wonderful gems and minerals exist in our world – all in one place. There are several gem and mineral shows which are held between December and late February in this town, which swells to over a million visitors in the month of January from a paltry 3,714 +/- residents the rest of the year. One of our favorite shows to check out is the QIA Pow Wow, which takes place this year from January 19 – 23, 2022, with free admission and free parking and way more than a day’s worth of treasures to see. It’s like a giant open air swap meet held under the beautiful blue sky with giant puffy white clouds floating overhead – which sometimes open up with a quick light rain or a heavy shower – then dissipates as quickly as it starts. Quartzsite is just 18 miles east of the California border, along Interstate 10. One can make it a full day trip, or if you’re able to secure lodging in Quartzsite or Blythe, CA, turn your visit into more than one day so you can visit the other shows taking place as well, such as Tyson Wells or Desert Gardens. If you prefer to take an RV and camp, there’s plenty of open space just on the outskirts of town. How to get there? Take I-10 East until you get to Quartzsite, about a four hour drive from Pasadena when traffic isn’t bad. We often make a quick stop at Chiriaco Summit either on the way to or from AZ, where one can fuel up and stop for a bite or snacks.
