Signed Alexis Bittar large pendant necklace with a long chain, versatile in color and design, this necklace features a 2 3/4" X 1 1/2" Pendant with black stone which I believe to be black onyx but I am not certain of that. The black stone has a small amount of white "matrix." The gold plated chain is 32 inches long. This necklace is in very good condition.
