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.
