1. A method of transferring gem identification information onto a jewelry setting for the gem, comprising:
obtaining the gem;
obtaining the jewelry setting comprising an upper layer of a first metal and a lower layer of a second metal that is more susceptible to oxidation than the first metal;
determining gem identification information including at least one salient property of the gem;
transferring the gem identification information to the jewelry setting, at least in part by using a laser to engrave the determined information through the first metal to expose the second metal, and subjecting the exposed second metal portion to an oxidization process to impart a color that provides a contrast to a color of the first metal to enhance visibility of the transferred gem information;
wherein the oxidization process comprises applying a liquid sulfur oxidizer to the exposed second metal portion to darken the exposed second metal portion and applying a second liquid oxidizer to the exposed second metal portion to further darken the exposed second metal portion; and
mounting the gem on the jewelry setting.
