The name Tourmaline from the word toramalli means mixed gemstones.
This beautiful gem has been used in the past, but little is known about it. The Portuguese found a beautiful stone in Brazil that they thought was emerald, but it was a beautiful tourmaline green. This gem was more widely known in America by the efforts of the famous gemologist George F. Kunz (discoverer of Conzit) who introduced this gem. In the early twentieth century Brazil became one of its most important sources of supply and work on tourmaline resources, which is now the most important source of tourmaline.
