Vapor is track #8 on the album Sounds Good Feels Good.
Increases physical strength. Soothes and calms emotional stress. Opens the 3rd eye to the divine. Very visual and creative. I must admit that I have never heard of black amethyst so if im not mistaken in my thinking, it is the same thing as amethyst but appear black because of the dark coloring in it.
In the psychic and spiritual realms, amethyst is an excellent all-purpose stone that can increase spirituality and enhance intuition and psychic powers of all kinds. It does this by making a clear connection between the earth plane and other planes and worlds.
