Vintage Art Deco 1930s 18K .10 carat diamond engagement ring

An American-made WWII Era diamond engagement ring. The ring features a modest Old European Cut diamond bead set in a square head. Little etches at the compass points in the head, as well as milgrain detail, give the illusion of a larger gemstone. The ring has flanking single cut diamonds on the shoulders and a svelte knife edge shank. The ring is stamped "Bluebird" inside, which was the brand name of a bridal line for a Chicago Company. "Bluebird" brand rings came with beautiful warranty certificates (see an example in the photos).

Measurements: Size 5 3/4 US, 1.7 grams. This ring may be sized in the 4-7 US range for $75.
Diamond details: (1) Old European Cut diamond, .10 carat VS/G-H and (2) .025 single cut side diamonds
Era: 1920s-1930s
Markings: 18K and BLUEBIRD
