Abstract
A colored sapphire material and methods for coloring sapphire material using lasers are disclosed. The method for coloring the sapphire material may include positioning the sapphire material over an opaque substrate material, exposing the opaque substrate material to a laser beam passing through the sapphire material to impact the substrate material, and inducing a chemical change in a portion of the sapphire material exposed to the laser beam. The method may also include creating a visible color in the portion of the sapphire material as a result of the chemical change. The colored sapphire material may include a first transparent portion, and a second, colored portion substantially surrounded by the first portion. The second, colored portion may have a chemical composition different than that of the first portion.
