Emerald Cut Lab Grown Diamond Engagement Rings

An emerald cut uses long, parallel step facets that give broad flashes of light and a clean, architectural look. Because step cuts show a stone's clarity and color plainly, they reward a clean diamond. Made to order in 925 silver, 10K, 14K or 18K gold, or platinum.

Flashes, Not Glitter

Instead of many small triangular facets, an emerald cut has rows of long, flat steps. They work like a set of mirrors, so the stone shows calm, broad flashes and a see-through look often called a hall of mirrors. It is the shape for someone who likes clean lines over busy sparkle.

Why Clarity Matters More Here

Those open steps make it easy to see into the stone, so inclusions and color that a brilliant cut would hide can show. Our emerald cut listings describe the centre stones as E-F color and VVS clarity, which keeps the stone looking crisp and bright.

Ratio and Size

Most emerald cuts have a length-to-width ratio of 1.30 to 1.50; around 1.40 is the classic rectangle. As a guide, 1 ct is about 7 x 5 mm, 2 ct about 8.5 x 6.3 mm and 3 ct about 9.5 x 7 mm.

Emerald, Asscher or Criss Cut?

An Asscher cut is the square version of the same step-cut idea. For a rectangular outline with more sparkle, see the radiant cut. The same shape in moissanite is in our emerald cut moissanite rings.

Common Questions

Does an emerald cut sparkle less?

It sparkles differently: fewer, broader flashes instead of many small points. Many people prefer its calm, glassy look.

How big is a 1 carat emerald cut?

About 7 x 5 mm, depending on its ratio. Because it is long, it looks larger than a 1 ct round from the top.

What ratio should I choose?

Around 1.40 is the classic rectangle. Choose lower for a squarer look or higher for a slimmer, longer stone.

Emerald cut or Asscher cut?

Both are step cuts. An emerald cut is rectangular; an Asscher cut is square with a more noticeable windmill pattern.
