Selenite is a gorgeous stone that has a unique texture.  When a candle or light is placed inside/behind a piece of Selenite, the colors shine through in a beautiful display.  Selenite is often called "nature's fiber optic" in the way that light passes through it.  Put a tealight candle in this holder and turn the lights down for a beautiful flicker and glow.  Measures approx. 4.5" in diameter, but each will vary.
