Bottom Line Recommendation
It’s often tricky to decipher the Cut quality of an Emerald Diamond—and preference of a more square vs. elongated shape is largely based on personal style. Because of these unique factors, the range of acceptable depth % changes from diamond to diamond.
To find an Emerald Cut Diamond that’s stunning and also high in value—without a giant price tag—we encourage you to contact us directly for assistance and advice.
The Emerald Cut Diamond flaunts an elongated, rectangular shape and chiseled step cuts, with straight linear facets—usually arranged parallelly down the stone. To add stability and prevent fractures, the corners of an Emerald Cut Diamond are usually cropped.
The Emerald Cut Diamond provides for deep clarity and a large surface table. Through its long step cuts, the diamond offers abundant reflections both of white and colored light. Emerald Cuts are more prominent in rectangle but are available in square as well.
A popular choice for those wanting a larger stone without a high price point, an Emerald Cut diamond usually appears bigger than other shaped diamonds in the same carat weight.
Emerald cuts fit well in many different styles, but they really fit perfectly with more understated settings. Emerald cuts go well with solitaire and simple pave settings, and are perfect for three stone settings. Take a look at this stunning three stone ring.
While there’s no industry wide consensus on what Cut parameters make an ideal Emerald Cut, there is a range we recommend to maximize luster. The GIA grades polish and symmetry on fancy shapes, like the Emerald, but does not grade on Cut.
|Table %||61-69||57-60 or 70-72||54-56 or 73-74||51-53 or 75-79||<51 or >79|
|Depth %||61-67||59-60.9 or 67.1-70||57-58.9 or 70.1-74||54-56.9 or 74.1-79||<54 or >79|
|Girdle||Very Thin – Slightly Thick||Very Thin – Thick||Very Thin – Very Thick||Extremely Thin – Extremely Thick|
|Length/Width Ratio||1.40-1.50||1.30-1.39 or 1.51-1.60||1.20-1.29 or 1.61-1.80||1.15-1.19 or 1.81-1.90||<1.15 or >1.90|
Measured by dividing the diamond’s length by its width, the length to width ratio tells how proportionate the diamond is with its intended shape (i.e. rectangular vs. square). For example, if a diamond’s length is 6mm and its width is 4mm, the length to width ratio is 1.50.
A classic rectangular Emerald Cut Diamond ranges from 1.30 to 1.60, while most people choose a ratio close to 1.50. Review a handful of Emerald Cut diamonds to determine which length to width ratio you prefer. Consider also how the diamond will look in your desired setting.
If you prefer a more square shape—instead of a rectangular design—you may wish to consider an Asscher Cut Diamond, an exquisite alternative to the Emerald Cut.
The GIA scale for Clarity ranges from best (void of inclusions) to worst (easily noticeable inclusions). Their designations include:
The table (top surface area) of an Emerald Cut is like a clear unobstructed window into the center of the stone. Any inclusions found in the middle will be clearly visible. Because both the pavilion (the bottom slanted portion of the diamond) and crown (the upper diamond resting atop the girdle) are comparatively shallow, Step Cut stones are generally not as bright and never as fiery as brilliant cut stones. Rather, they accentuate a diamond’s Clarity, as even the slightest flaw would be highly visible.
In other words, blemishes in an Emerald Cut Diamond will be more noticeable than in a Round Cut Diamond or Cushion Cut Diamond.
For this reason, we recommend a VS2 Clarity for the best value, like this Emerald Cut Diamond in a rose gold solitaire setting. SI2 and SI1 clarity grades are generally not recommended with Step Cuts such as Asscher Cuts and Emerald Cuts. Step Cuts aren’t cut for their brilliance, so there’s no scattering of light to hide inclusions.
Most importantly, review all possible diamonds carefully to ensure they look clean to the naked eye. If you’re looking for an SI1 or SI2 Emerald Cut, for example, you must verify that inclusions are not in the center of the stone.
For the best tool in evaluating an Emerald Cut’s Clarity, we suggest James Allen’s ultra-high quality diamond photography. Their technology provides up-close photographs for reviewing stones in detail.

Similar to Clarity, Color is another attribute that is more noticeable in an Emerald Cut. Its large table and step cuts retain more color than other Diamond Shapes, allowing the eye to see the natural Color of the stone.
The GIA grades Color on a scale from D to Z. D is the most colorless while Z contains easily noticeable brown or yellow tint.
When you look at an Emerald Diamond of a J grade or higher with the naked eye, you can easily notice a slight yellow tint. Because the naked eye notices no tint at an I Color grade or better, we recommend this range for the most beauty and best value. If you choose a diamond below an I, such as a G or H, you will likely not notice much of a difference—if any at all. Paying more for a lower Color grade is usually not worth the additional price.
It’s also important to ensure your diamond looks white in relation its setting. For example, this stunning I color Emerald Diamond in a white gold pave setting bursts with white, radiant color. Even this J colored Emerald looks shimmering in a rose gold setting. Overall it’s important to review the Diamond’s Color and setting before purchasing.
Take a look at the size differences between different carat weigh of an emerald cut. Keep in mind that those are average measurements as every emerald cut diamond is slightly different (in measurements and L:W ratio).
The simple answer is yes. An engagement ring with an emerald cut will be cheaper than an engagement ring with a round diamond (and cheaper than most other shapes). Emerald cuts are cheaper per carat than most cuts, and are significantly cheaper than round diamonds. This is due to two factors: lower demand for emerald cuts and higher yield on cutting (you lose the least amount of weight when cutting a rough diamond into a polished emerald cut.
But things are not that simple. Yes, emerald cuts are cheaper. But you also need to be far more strict when choosing an emerald cut. Due to its glassy nature, emerald cuts do not hide inclusions nearly as well as other cuts. We normally find SI1 or SI2 clarity grades when selecting a diamond for our readers. When we are selecting emerald cuts, it’s usually a VS2 or even VS1 clarity grade.
Take a look at this emerald cut. Usually an SI1 clarity diamond like this would be eye-clean. Unfortunately, due to the large table and glassy nature, the inclusion is visible to the naked eye. That doesn’t mean that emerald cuts are a poor choice. As we mentioned, emerald cuts are cheaper per carat. You can upgrade in clarity and still get a good deal.
Emeralds and asschers are pretty much identical. The only discernible difference is L:W ratio. Emerald cuts are traditionally rectangular while asscher cuts are square. From a value or quality difference, there is no difference. It all boils down to personal preference or setting style.
Emerald cuts have a glassy, understated elegance to them while cushion cuts have a softer, more modern look. Cushion cuts will exhibit more brilliance and are the more popular cut. Emerald cuts cater to someone looking for a classy, timeless look.
Emerald Cut Diamonds offer an elegant shape and unique Step Cuts. Emerald Cuts are a phenomenal choice for those desiring a larger looking Diamond without a hefty price tag.
