This vintage 18K white gold solitaire ring band has a four-prong stone setting and Art Deco styling. It is a size 5 1/2.
The shoulders of the ring band taper slightly and have cast geometric designs in blocks with an “X” on each end (a kiss, perhaps?)
Inside the ring is stamped 18K with a sideways Characters (M or an E). The ring is in very fine condition. Total weight is approximately 1.2 grams.
Set with a diamond, this would be a lovely engagement ring. Try a colored stone, and you’ll have a fine white gold ring with distinctive vintage style.
