20s Art Deco Rock Crystal Necklace with Sterling Clasp

'20s Art Deco Rock Crystal Necklace Sterling Clasp Vintage necklace from the '20s. This Art Deco Rock Chrystal necklace is in perfect shape. It is still originally strung with a Sterling Silver push clasp. The crystals are faceted and are flat rather than round. Between each large crystal are two small crystals. The necklace is graduated to the center. The center crystal is about 3/4". I have had it for 35 years and got it from a friend who said it was her grandmother's! It is truly beautiful piece of history! Thank you for looking!
