The body has an inner surface, an outer surface, and a wall thickness extending between the outer surface and the inner surface. The marking is located within the wall thickness. In particular, the marking is a portion of the body having a refractive index that differs from a refractive index of an unmarked portion of the body. Methods of forming the marking within the body are also described.
