This is a simple clear glass ball or orb with one end sliced for a flat surface. The flat end is coated with a silver paint that reflects iridescent colors through the solid glass. From some angles, the ball is clear, from some angles you can see some color, and from some angles you get the full color experience. It is 2 3/8" wide. It is not marked or signed. The paperweight is in excellent condition. There is a bit of wear to the silver paint.
