When I first saw this ring, I thought it was not costume - but onclose inspection, the opal is iridescent glass and there are no marks on the band. It is size 8.
We have a number of costume jewelry rings that were samples and unsold merchandise from a shop that closed several years ago. The may be faux, but all are fun! Most date from the 80's and 90's.
This ring is in very good condition,with the slightest of "shop wear".
