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.
Amethyst is the violet-colored sister stone of golden citrine quartz. Color-zoned ametrine is the bicolored combination of both amethyst and citrine. The only difference between amethyst and citrine is the level of iron impurities in amethyst.
