Jewelry Design Dancing Ballerina Kinetic Cocktail Ring by Margarita Prysiazhniuk Dancing Ballerina is a kinetic cocktail ring inspired by the Hans Christian Andersen tale of the tin soldier and the paper ballerina. A rotary mechanism inside the ring allows the ballerina figure to turn with the slightest movement of the hand. The figure is made of 18k white and yellow gold and set with 223 white diamonds of 4.03 carats in round and pear cuts. The ring measures 5 cm in diameter and 5 cm in height and weighs 37.20 grams. A double-flip coin base allows the ring to stand as a small sculpture when it is not worn.
