It is also split in the back, and measures around a size 7. The hallmark says G &AB, and "Sterling" is written in cursive. Ring #5 is just past size 6.5 on my ring measuring tool. The stones are similar to those in ring #4 but with a bit of gold variegation, particularly on the large central oblong stone.
There is no hallmark, but the reverse side has the mottled metal look of an older piece. For many years my grandmother traveled to shows across the Southwest collecting coral, turquoise and lapis jewelry and belts. They were part of her signature look back when she used to go country line dancing at The Cowboy Palace. Most of these items have remained untouched in boxes since she broke her ankle 15-20 years ago. If you're into Native American jewelry, you may want to keep tabs on me since her collection is extensive and she's only beginning to part with it.
