Natural Untreated San Diego Tourmaline Mine California Pink Tourmaline

These beautiful, natural Hot-Pink Tourmalines come from the now closed San Diego Tourmaline Mine.

The rough tourmaline crystals were obtained while we owned the lease on the mine, and the cabochon cuts were done in India to our specifications about a year later.

Natural pink tourmaline gemstones over 1 carat are rarely eye-clean. The beautiful colors of these stone, their size, history and mine source and cut place them stone at good quality on the consensus of major grading scales.

The San Diego Tourmaline Mine has been owned by the same family for four generations. It and the Himalaya mine are adjacent on the same pegmatite vein in San Diego County, California and have produced many colors of tourmaline, but are particularly known for production of high quality pink, red, green, blue and multi-color stones. This double-veined pegmatite was a mineralogical phenomenon even in its prime, and still discussed in gem institutes and university geology departments today. Stones from this mine are found in several major museums and private collections. The tourmaline deposits of southern California, including the San Diego Tourmaline, Himalaya, and San Diego Tourmaline Mine mines, were part of a boom in tourmaline mining in San Diego County between about 1890 and 1910, when the dowager empress of China and her court were buying most of the production of pink tourmaline.
