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.
The location where amethyst is mined has a big impact on its appearance (saturation, distribution of color and formation too). Amethyst generally ranges in color from pale pink to light purple (violet) to dark blue violet. It can also include shades of red and gray. Uruguay is best associated with amethyst that has a deep purplish blue color. The same is true for amethyst which comes from Arizona, Russia and Africa.
