Tourmaline - Stewart Mine, Tourmaline Queen Mountain, Pala, California, USA
 ex collection Robert Scheck
 
 Intense, almost neon-like pink on this tourmaline from the Stewart Mine in the Pala District in California. In terms of color, some of the best Rubellites in California come from the Stewart Mine, comparable to the rich red of the famous Queen Mine, which produced the most expensive tourmalines.
