Mid Century Vtg Art Deco 10K Yellow Gold 3-Diamond Filigree Statement Ring Sz 7

In good condition. It is hard to read but it looks like it has a GTR stamped next to the 10k and there is also a 7 and a moon crest. The inside has some scratch marks when you look through a glass finder. So it will need a cleaning and a good polish. See pictures for details.
