Abstract
A flexible method to provide a variety of value-added coatings to a piece of jewelry or a group of jewelries is disclosed. Atomic Layer Deposition (ALD) and Molecular Layer Deposition (MLD) technique is implemented to deposit a layer of conformal coating on intended jewelry surfaces, including both exterior and interior surfaces, to enhance a vast majority of process-driven or end of use driven properties. The coating compositions include dielectrics material, metals, organic materials or organic-inorganic hybrid materials. The method steps of forming a layer of coating are straightforward and can be tailed to different purposes.
