Tourmaline’s name comes from the Sinhalese word “turmali,” which means “mixed.” Tourmaline, occurring in more colors and combinations of colors than any other gemstone variety, lives up to its name. Known for centuries, tourmaline first gained popularity when the Dutch began to import it in the early 17th century from Sri Lanka . Tourmaline is actually the name of a group of related mineral species. In gemological practice, individual species names are not used. Instead, all are simply termed tourmaline.
