Antica Murrina ring. Made in Italy

Antica Murrina handmade glass ring from Italy in light pink, bright pink, green and navy/black. In original box with pamphlet describing the process. At the widest point it is almost 1 inch wide, this part fits across the top of the finger. There is no indication of ring size but it fits me and I wear a size 7 on my ring finger. In perfect condition.
