摘要： A method to permanently mark an item of laminated jewelry involves creating a laminate of two metals, and upper layer typically formed of a more precious metal such as gold, platinum or palladium that do not readily oxidize laminated onto the surface of a less precious metal, such as silver, which can be 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 thereof 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 then used to blacken the silver, typically a dark gray. However, if more contrast is needed by making the marked text, designs etc. darker than gray a second step can be used by applying an additional oxidizing agent to turn the dark gray to substantially black.

摘要： A jewelry ring having a main ring with two half-ring segments, where each of the ring segments has its own design. The design of the first ring segment is more prominent than the design of the second segment and is typically displayed to an outside viewer. However, when, for security or any other reason, the wearer rotates the ring, the second half with the less prominent design is displayed, concealing the more prominent design of the first half without alerting a robber that a more prominent design is hidden.

摘要： 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.
