Gneiss is an old German word meaning bright or sparkling.
Warming, stimulating, clarifying and calming. These yellow stones help to relieve stress and may also help to clear depression. They aid the emotions and creates a more positive outlook on life.
Gneiss, arguably, is more visually interesting. It’s characterized by stripes, linear bands, or flowy rivers of color. This pattern is called foliation and it’s a result of the rock being squeezed and heated.
