Emerald

An emerald cut is a step cut: long, parallel facets instead of lots of small ones. Rather than sparkling, it gives off broad, glassy flashes of light, a bit like a hall of mirrors.

It's the shape with the most old-world glamour. Think Art Deco, clean lines and quiet confidence. If you love a vintage feel but still want something that looks modern on the hand, this is often where people land.

One thing worth knowing: those large, open facets show you exactly what's inside the stone, so clarity matters a little more here than it does with brilliant cuts like an oval or round.

FAQ

Is an emerald cut a good choice?

If you prefer clean lines and a softer shine over maximum sparkle, it’s a lovely choice. It also tends to look generous for its carat weight thanks to its long shape.

Do emerald cuts show flaws more easily?

They can in a lower-quality stone, because there’s nowhere for an inclusion to hide. Since every Una diamond is high clarity and IGI certified, you get the clean, glassy look the cut is known for without that worry.
