Dark cognac glass flower cocktail ring

Amber, coppery (in some light they look bronzy) crystals raised center crystal gold tone finish on band- band is adjustable origin unknown (my Mom's) on the mandrel it measures a size 8.5 an inch across Flaw- inside band shows tarnish or gold tone wearing off. Also feel slightly rough in some spots. Could be buffed out or filed. Outside under flower petals the band has a tiny tarnish but when ring is on, you can't see it. Good condition. My Mom bought for an event and wore once.
