This 1950's vintage ring has never been worn. It, and a few others have been residing in the back of a bank vault for decades. It was made in Buffalo, NY in the late 1950's of 10K solid yellow gold and prong set with a beautiful lab grown blue spinel which measures 8 x 6.6 millimeters rectangular. The stone is step cut. The streamlined Art Moderne motif of this ring makes it a real find! The ring is currently a size 5 3/4 but could be sized easily to fit your finger.
