Sterling silver opal ring. 7.5 , 8

Here is a vintage genuine opal ring. Metal is stamped 0.925 sterling silver. The design on the sides continues all the way around. Ring is approximately a size 8, perhaps 7.5. Measurements available upon request. There are a couple small hematite stones on either side. One of the hematite stones is broken (pictured in picture #3). It is really not noticeable unless being closely examined. Opals are the birthstone for October.
