A method to permanently mark an item of plated jewelry involves creating a laminate of two metals, and upper layer typically formed of a more precious metal such as gold, platinum, and palladium that do not readily oxidize, laminated onto the surface of a less precious metal, such as silver, which is oxidized to create a dark color (e.g. black). A laser is used to create characters and/or designs in the upper layer by vaporizing portions to effectively remove those portions. This exposes the upper surface of the less precious metal that does become oxidized. An oxidizer, such as liquid sulfur, is used to blacken the silver, typically a dark gray. This allows an easy and inexpensive method of archiving information on jewelry bearing or supporting a gem that describes the supported gem rendering the gem more valuable collectible and traceable.
