Capistrano Mining Company is an online store. I do not have a traditional brick and mortar store.  I sell through this website, other online sites and auctions, as well as selling at gem and mineral shows in California and Arizona. I do mine and rockhound to bring new great items for sale, but do not have any place for the public to mine. However if you would like to find places to actually dig for your own gems and minerals while in California or Montana, please look at our "Links" page or send me an email.

I provide rockhounds, future rockhounds and treasure hunters, mine run gravel from the Sapphire mines of Montana, Benitoite mine run ore gravel and specimens from the one and only Benitoite Gem Mine in San Benito County California, and Tourmaline mine run ore gravel from the world famous Tourmaline district of San Diego County, California. 

I bring the ability to mine for these rare gems and specimens, right to your home! No gimmicks, no tricks, no "High-grading", just gravel direct from the mines for you to search. A true treasure hunt for all to enjoy. If you cannot get to the mines to dig, then our packages are the next best thing! I have hundreds of extremely satisfied customers from all over the globe each year.

 I also supply jewelers, designers and the lapidary trade, gemstone rough, specimens and faceted gemstones for beautiful jewelry designs.
