ABSTRACT:
Methods of fabricating improved gemstones and gemstones thus obtained are described. Roughness is introduced on facets of a gemstone through application of nanometer and/or micrometer sized features, to provide the facets with a hazy white-colored appearance. Alternatively, millimeter-sized reflective features can be applied on the facets, to form a gemstone with improved scintillation or play of light.
