Because it is one of the October birthstones, black tourmaline jewelry is also sold as birthstone jewelry. Opal is yet another birthstone for the month of October! Black tourmaline is also the traditional gemstone for the 8th wedding anniversary, so don't be afraid to give your loved one a black tourmaline ring, pendant, or bracelet on your anniversary. Crystal healers and the spiritual community frequently use black tourmaline in the form of jewelry. Black tourmaline gemstone jewelry is worn by even the New Age community because it effectively absorbs environmental electromagnetic fields (EMFs) and can protect the wearer from electromagnetic radiation.
