Emerald Cut Engagement Rings

The emerald cut is a rectangular step cut with long, clean facets that create a quiet, mirror-like elegance rather than fiery sparkle. It is closely tied to the Art Deco era and its love of geometry. This collection features emerald cut diamonds and colored stones in antique and estate settings, hand-selected by Annette and Elan Brandt and authenticity guaranteed.

What is an emerald cut diamond?

An emerald cut is a rectangular step cut with cropped corners and long, straight facets. It produces a subtle, hall-of-mirrors shine rather than sparkle. The name comes from the cut traditionally used for emeralds, though it is popular for diamonds too.

Why are emerald cuts linked to Art Deco?

The emerald cut's clean geometry matched the Art Deco love of straight lines and symmetry, so it appears often in 1920s and 1930s rings. Choosing an emerald cut antique ring gives you that authentic period look with genuine craftsmanship.

Do emerald cut diamonds show inclusions more?

Yes. The open, step-cut facets make inclusions and color easier to see, so clarity matters more than in a brilliant cut. We describe each stone honestly and can walk you through what to expect before you buy.
