I google search the related information and benefit of tourmaline,
based on global healing center :
Tourmaline gemstone is a semi-precious mineral similar to granite. With colors ranging from magenta to teal-blue, meadow-green to vibrant yellow, and even black, tourmaline gets its name from the Singhalese phrase “tura mali,” which means, “stone mixed with vibrant colors.”
