  • Coatings for gemstones and other decorative objects
    Patent number: 7137275
    Abstract: The invention provides a decorative object comprising a transparent or translucent substrate having a body and at least one surface bearing a thin film coating. The coating imparts in the substrate a body color that appears substantially constant at different angles of observation. This body color is imparted in the substrate at least in part by absorption of visible radiation that is transmitted through said coating. The coating includes a high absorption layer comprising film that is highly absorptive of visible radiation. Also provided are methods of coating gems and other decorative objects, as well as methods of heat treating coated gems and other decorative objects.

  • Method of improving the color of transparent materials
    Patent number: 5853826
    Abstract: A faceted gemstone having at least one thin layer of material coated on the pavilion of a transparent substrate so that the body of the gemstone appears to have a different color. The color of reflected light changes hues when viewed through the face of the gemstone at different angles of observation. This causes the gemstone to appear to change color when the stone is tilted. The thin film is coated by low temperature techniques such as sputtering.
