Arts Of Creation Black Tourmaline ORGONITE Round (3.5 inch Coaster) Coaster Crystal Healing Reiki FENG Shui Gift Psychic Energy Metaphysical Gemstone Health Meditation Fear Deflector Spiritual Luck

Love it. I use it every day when I'm working and lay it right on my chest when anxiety or negativity arises

The "coaster" plastic case that holds the Tourmaline looks like it was used as a hockey puck - it has many, many scratches on it. Very dissatisfied! As for the reason of purchase- the black Tourmaline itself - I don't know how well it will do ask of yet.
