In accordance with the present invention, there are provided methods for imparting abrasion wear resistant color to "gemstones" by providing an integrated coating consisting of the color imparting agent and the abrasion wear resistant agent. The color imparting agent may provide the perception of color via interference phenomena or via bulk absorption phenomena. Abrasion wear resistance may be provided by integrating any of the materials such as DLC (diamond-like carbon), CVD diamond (CVDD), alumina, polymer-based materials, nitrides and carbonitrides. Abrasion wear resistant properties of DLC or CVDD may be further improved, in addition to improvement of other mechanical properties and inducing hydrophobicity, by incorporating certain elements into the deposited film. |
