This lovely Art Deco pendant necklace contains a slab of camphor glass with a .02 carat diamond set in the center and finished in 14 karat white gold. Camphor glass comes from a process of treating clear glass with hydrofluoric acid vapors to create a frosted appearance. The borders of the glass are made of amazing filigree wires overlapping. Even the slide on the pendant is beautifully designed with filigree wires overlapping. The chain on this necklace is made of 18 karat white gold.
