A uniquely faceted retro travel ring. It was made as a safe travel piece , while the real yellow saphirre or diamond ring set in 18k remained  under lock and key.  The rectagular stone has a fancy cut and is bezel set in gold with a fine gold braid wrapping the setting beautifully.  The travel pieces were usually set in 8 or 9kt in UK and 10k in the US. The shank on this ring shows no stamp.  Am pricing it as gold filled   Very Good Vintage Condition  please view photos carefully  approx. size 4 Yellow Rectangular Gemstone Rings, Classic Yellow Faceted Rings, Classic Yellow Rectangular Rings, Formal Yellow Rectangular Rings, Hallmarked Rectangular Emerald Ring, Yellow Rectangular Anniversary Ring, Vintage Yellow Rectangular Jewelry, Vintage Gold Rectangular Emerald Ring, Art Deco Gold Rings With Rectangular Stone
