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.
Claims16
A method for enhancing optical properties of a decorative object being composed primarily of a transparent or translucent substrate comprising the step of vapor-coat a part of the surface of the substrate with a first layer of a first coating material at a low temperature, wherein the color of light reflected from the decorative object to a viewer changes with an angle of observation.
A decorative object comprising a transparent or translucent substrate wherein a part of the surface of the substrate is vapor-coated with a first layer of material, wherein the color of light reflected from the decorative object when viewed from one angle changes to another color when viewed from a different angle.
