Signed 18k and Ceramic Moving Ring

An unusual designer-made piece crafted in 18k yellow gold and ceramic, hallmarked “JUNG”. I love the ability to swivel the two pieces to create different looks- align them to be an even width all the way around or have a wider peaked band.Ceramic used in jewelry is not like the type we eat off of- it’s a durable material resistant to scratches and quite lightweight. Chanel, for one has commonly incorporated ceramic in their fine jewelry collections.I have done some research on the hallmark but unfortunately have not confirmed who made this piece!18k and Ceramic Moving Ring - 16.6g - Size 7.5 (not sizable)- 10mm wide - $1,795
