Antique 1920s Art Deco 18K sapphire and diamond engagement ring

A gorgeous, all-original Art Deco engagement ring with a .56 carat Old European Cut diamond, exquisite mounting details, and bright blue sapphire accents. The design of this ring is superb and one of our favorite diamond + sapphire bridal pieces that we have found of late! This ring includes all of "greatest hits" of Art Deco bridal design: engraved shoulders, a pretty side gallery, contrasting colored gemstones, and a playful Old European Cut diamond. This particular design displays more linear elements than most Art Deco engagement rings, which we like a whole lot. Someone put a lot of love into crafting this ring and there are thoughtful details throughout. The look of the plump diamond squared off with corner prongs and lifted ever so slightly above the body of the ring . . .  perfection! 

Measurements: Size 7 1/2 US, 3.0 grams. This ring may be sized in the 6-8 range for $75.
Gemstone details: (1) Old European Cut diamond, .56 carat VS1/F and (2) .02 carat single cut diamonds and (4) straight baguette blue sapphires, .40 ctw blue sapphires. 1.00 ctw for the ring.
