It's rare to find this particular RC champagne necklace with the charm. It features an 18k white and yellow gold champagne cork accented with .65 ctw of brilliant white pave diamonds and a signature Roberto Coin ruby on the bottom of the cork. The adjustable chain is 14 1/2" to 19". The cork (as when suspended on chain): 19/32" (15.0mm) tall (from stationary bail), 5/8" (15.5mm) wide. It is stamped with the RC hallmark "18kt 1226VI Italy." Condition is EXCELLENT! Comes with the RC plastic bag.
