The most productive tourmaline mine in North America:
The Himalaya

This 40-minute video is a recording of a presentation on the history, geology, and mineralogy of the famed Himalaya Mine in the Mesa Grande District of San Diego County California given at the 2013 Dallas Mineral Collecting Symposium. This famous locality has produced gem quality tourmaline in a variety of colors, as well as beryl, lepidolite, topaz, garnet, feldspar, quartz, and several REE minerals. Mining activity began in the late 1800's and at the turn of the century it was producing carving-grade tourmaline for use by the Empress Dowager of China. Over the past century it is estimated to have produced about 90 tons of tourmaline much of it used for gem material, and more recently, high value mineral specimens. Bill Larson has owned and collected at the mine and is a good storyteller and his presentation has many pictures of the mine and its minerals.
