This is old Mike the Miner, and we're here at our Tourmaline mine in the high desert of San Diego County, world famous for semi-precious gemsstones like Topaz, Aquamarine, Beryl, Morganite, Kunzite, Garnet, Chalcedony and of course Tourmaline.

We've been mining and prospecting these hills, and visiting gem shows throughout the southwest, for about 30 years now. During that time we've collected a wide variety of precious and semi-precious gemstones, rare mineral specimens, museum-grade pieces, ancient coins and antique jewelry.

Our mine is called the Crystal Cave, and inside you'll find treasures from all over the world, exotic locales like Brazil, Colombia, Mozambique, Tanzania, India, Burma...and San Diego. You're welcome to browse around our Fine Gems Emporium, Tourmaline Station, The Lee Treadwell Collection Estate Sale, The Crystal Caverns, and our "Free Stuff" Annex.

Our most recent additions are Bismuth Crystals. You'll see one to the left in our rolling-frame pictures These multi-rhombic rainbow-colored creations just might be the most staggeringly complicated, yet stunningly gorgeous, crystalline structures on Planet Earth. Enjoy!
