Art Deco Camphor Necklace w/ Single Cut Diamond.  This whimsical pendant from the Art Deco period contains a slab of camphor glass with a .02 carat diamond set in the center and finished in 10 karat white gold. Camphor glass comes from a process of treating clear glass with hydrofluoric acid vapors to create a frosted appearance. At the top and bottom of this camphor slab are triangular sections of filigree wires.
