Southern California is known worldwide for the production of gemstones and mineral specimens from granite pegmatites in San Diego, Riverside and San Bernardino Counties. Some of the more well know gem minerals are tourmaline, garnet, aquamarine, morganite, kunzite, quartz, topaz and lepidolite.

Most notable are the Pala and Mesa Grande mining districts that supplied beautiful tourmalines to the Dowager Empress of China in the early 1900's. 

This talk will include discussion on the regional geology which made these deposits possible, history of mining in Southern California, and some of the more important mines and the gem minerals that they produced.
