The Emerald, Ruby & Lapis options are “Doublet Gemstones”. A Gemstone Doublet is a thin slice of natural gemstone (emerald, ruby and lapis) “fused” together with a faceted “top” of Rock Crystal, to give the piece luminous sparkle. The emerald option has an additional third bottom layer
of Mother of Pearl, for added strength and deeper color. These unique, labor intensive gemstones provide a colorful expensive appearance, without the price tag.
