The Tourmaline King Mine, high on the northwest slope of Queen Mountain near Pala, California, was opened in 1903 by F. B. Schuyler and quickly yielded a bonanza of gem-quality tourmaline crystals from a pegmatite running along steep slopes at around 1,600 feet elevation . The mine has seen sporadic activity into the 21st century. Though never as prolific as nearby operations, Tourmaline King remains prized among collectors for fine pink, green, and watermelon tourmaline specimens, with occasional crystals recovered from tailings and limited underground work. This specimen features a unique gray-blue shade, and a smaller terminated crystal on the main termination.
