over substantially the entire surface of the substrate. Claim 1 illustrative of the invention
and reads as follows:
1. An article of manufacture comprising a substantially transparent substrate of a
size and shape suitable for use as a decorative object selected from the group consisting
of gemstones and ornaments and a multilayer thin film interference coating over
substantially the entire surface of said substrate, said coating consisting of alternating
layers of substantially nonabsorbing materials with a relatively high refractive index and a
relatively low refractive index with respect to each other, the thicknesses and identities of
said layers being chosen so that the entire coating will preferentially reflect at least some of
the incident light with wavelengths between 400 nanometers and 700 nanometers
inclusive.
