Probably the most requested, most popular, best-selling item over at Walton's Antique Jewelry (where I work as a Gemologist) is the Art Deco Diamond engagement ring. Since being there for over a year now, I've come to realize how each one is unique--different filigree patterns, different prong styles, different hand-engraved motifs. Each however, has one thing in common--an Old European cut diamond set in the center. Whether its clarity is a VVS-1 or SI-2, or its color is a colorless D or very yellow Q, each is special because it was cut by hand rather than lasers. A. Brandt & Son has some great Art Deco engagement rings for sale, take a look at my favorites below. And if you are ever in the Nashville area, stop by Walton's Antique Jewelry--I can show you the hundreds we have!
