Striking vintage strand of faceted Rock Crystal Beads, dating to circa: 1920 (Art Deco period). Alternating between each faceted Rock Crystal Beads is a small, round green Onyx bead. Is quite effective and a gorgeous combination. The Crystal Beads are oval and of graduating size. The largest oval Bead is a good size, measuring 3/4" x 1". The strand measures 15 1/2" long. The largest Bead measures 5/8" in diameter. Is an unusual and absolutely beautiful vintage Crystal & Green Onyx Necklace. Is in fine condition and shows very well in the photographs and just as pretty in person! Photographs taken with and without a camera flash.
