Located about 60 miles east of San Diego, a new emerald deposit has been discovered in the Julian Mining District (figure 1). This area is known for pegmatite mines and hydrothermal mineral deposits; however, none of those are known to have produced emeralds to date. The emeralds (example shown in figure 2) were all collected by author RE and son Bruce Edley near the surface and are embedded in a biotite schist host rock. Most of the recovered single crystals have a translucent dark green color and inclusions, and they are typically smaller than 2 cm. A few light-colored green beryl crystals have been recovered from a nearby pegmatite. Their formation was likely correlated with metamorphic and hydrothermal processes associated with regional tectonism.

Yes, I was aware of that find. However, I have not yet had a chance to go and see it for myself. It is on my list of things to do.

Very cool! First the several in NC, then that little one in Montana and now California. I'm sure I am forgetting some other small US emerald locale here too.

Thanks daniele. I would be more inclined to call that green beryl than emerald. I have collected better specimens myself at Railway Dyke in Washington.
