Cloisonne is an ancient Chinese art form and its fabulous to see it transformed into a ring. Teardrop shape cloisonne front measures just over 1 1/2" on copper. The ring is an adjustable metal band. Forming a circle would be approx size 8 and of course you can bend in or our for larger or smaller. The band is quite mishapen. It would be a perfect piece to have a proper copper band attached to. The cloisonne is in excellent condition with a small nick or imperfection at the top. You'll have the most unique ring in town!
