Art Deco engagement rings are one of my favorite things. Just because I have an official one on my left ring finger now doesn’t mean I’m ever going to stop looking at them. (After all, I have 10 fingers.)

I look at diamond rings as sort of the LBD of the jewelry world. What a jeweler (or an era) does with a diamond ring is an excellent way to understand that person or time period’s overall design aesthetic. What you do with a small canvas says a lot about you. Some of these Art Deco beauties use color, but they’re all primarily white diamond. And they’re glorious.

Let’s start out with a dash of color. This circa 1930 Art Deco engagement ring stars a 1.02 fancy brown yellow diamond. The diamond is a hexagonal step cut set in an East-West style (that means it’s sideways) which is think is a wonderfull elegant touch. The platinum setting is embellished with single cut diamonds and hand engraving.

Have you ever seen anything more marvelously geometric than this ring? The 1.19 carat old European cut center stone is set within a wide halo of circular cut diamonds with delicate milgrain edges and two baguette diamonds.

Speaking of the geometric…how do you like this one? A slightly rounded take a classic setting, this glamorous ring enshrines a 1.63 carat diamond atop a step pyramid of single cut diamonds and millegrain details. It’s also lovely from the side.

This 2.03 carat showstopper is by J.E. Caldwell, circa 1920. The shoulder detail is so amazing that it hurts my heart.

Here’s an Art Deco engagement ring with onyx details. I just love the color contrast of the bright diamonds with the dark onyx.

This abstract, picture frame-esque ring is just too pretty for words. I love the lines, the subtlety, the engraved shank and – most of all – the sapphire accents.

This ring has the most interesting shoulder detail – I’ve never seen anything quite like it. This engagement ring is from 1920 and centers a 1.57 old european cut diamond a square box setting decorated by milligrain edges and accented by 3 single cut diamonds on each shoulder.

Let’s end on a sparkly, diamond-encrusted note. This Art Deco engagement ring is meant for a finger that not afraid to dazzle. An .80 carat center stone leads the explosion of sparkle on this platinum openwork setting covered with single-cut diamonds and finished with millegrain edges.
