What are an Emerald Cut Diamond’s Dimensions? 

The emerald cut is a rectangular, step-cut shape with trimmed corners. It’s low on brilliance, but compensates for its lack of sparkle with a hypnotizing “hall of mirrors effect”. 

Emerald cuts look larger than other shapes thanks to their large table facet. Their typical length-to-width ratio is 1.25 - 1.65, but square (1:1) emerald-cut diamonds also exist. 

About the Emerald Cut Diamond

The emerald cut is one of the oldest diamond shapes. Its origins go back to the table cut of the 1500s. At the time, stonecutters used the Emerald cut to shape emeralds. The shape’s step-cut anatomy meant there was less pressure on the soft gemstone during the cutting process. This prevented chipping and breaking. 

Later, diamond cutters began to cut diamonds in the same shape. In the 1920s, when the Art Deco movement was in full swing, the shape became a huge hit. Its “hall of mirrors” effect, clean lines, and geometric patterns were a perfect match with the day’s trends. 

Today, the Emerald cut is a popular alternative to the round cut, radiant cut, and oval. Its size and unique look make it a popular option for engagement ring buyers. 

Shopping for Emerald-Cut Diamonds

Emeralds have a larger face-up area than Asscher, princess, and cushion-cut diamonds. This makes them a good choice if you want to get more diamond for your dollar.

Emeralds have large, open facets that draw attention to the smallest imperfection.

But you don’t necessarily have to go for “flawless” clarity grades. VS1 and VS2 both work so long as your stone is eye-clean. If you’re not sure, use our 3D preview tool to make sure before buying. 

Like other step-cut shapes, emeralds show more color than brilliant cuts. If you want your emerald diamond to appear colorless, opt for H color or higher.


1. Do emerald cut diamonds look bigger?

Yes, elongated stones like emerald cut diamonds generally look larger. This is because the top surface is bigger than a round cut diamond of the same carat weight.

2. How big should an emerald cut diamond be?

Most emerald cut diamonds have length-to-width ratios ranging from 1.30 to 1.50. A ratio of 1.40 is considered ideal, but always consider your own preference when choosing a ratio.

3. Are emerald cut diamonds cheaper?

Yes. Emerald cuts are cheaper per carat than most cuts. They are especially cheaper than round diamonds. One reason is that there is lower demand for emerald cuts. Another reason is that the cutting process retains most of the rough stone's weight.
