As the saying goes, "variety is the spice of life". This is certainly true in the world of diamonds. Although the round brilliant is the shape most associated with diamonds, these amazing raw crystals of pure carbon are cut into a wide variety of shapes and facet arrangements. This creates many "flavors" of diamonds, some as different from each other as chocolate and strawberry. The emerald diamond is one of the most distinctive of these flavors, both in shape and appearance. In this article, we'll explore the unique beauty of the venerable emerald-cut diamond.

What is an emerald cut diamond?
Emerald diamonds have long been considered the most elegant diamond shape. They are very subtle in their overall appearance and the type of look they produce. The stepped-cut face design creates a completely different visual sensation from the ubiquitous round glitter and the many variations of glitter shapes available. The emerald cut features a series of horizontal, step-like facets, as opposed to the vertical facets of the brilliant styles. Its four longest sides have chamfered corners with two, three or four concentric rows of faces, parallel to the sash, on the crown and on the pavilion. In this article, you'll see how this single-facet style affects light performance and what to look for in this venerable diamond cut that's considered a classic for its old-world opulence.
What to Look for When Buying an Emerald Diamond
If you are looking for a loose emerald diamond, the information below will help you choose an excellent stone for your taste and budget. We will discuss aspects of the 4 C's such as clarity, color and especially the quality of the cut that will be fundamental for choosing a great diamond. We'll also discuss taste factors such as length-to-width ratio, as well as style considerations for emerald diamond rings. And we will discuss the prices of emerald cut diamonds.
Length/width and angle/width ratios
The overall shape of an emerald cut can vary dramatically from the square Asscher shape to the very elongated emerald cut. To a large extent, the outline of the figure is a matter of personal taste. Some prefer a long thin shape, others a wider rectangular shape. Most people prefer something in the middle – a balanced rectangle with a length-to-width ratio of around 1.4.
An emerald cut is an octagon with four sides and four corners. The overall length-to-width ratio (length in millimeters divided by width in millimeters) is very important in determining the visual appeal of the shape, but the size of the corners also has a visual impact. They can be very small, slightly cut corners, or large corners the size of the other sides.

Asscher Cut – Emerald Square Cut
A unique variation of the emerald cut is the Asscher cut. This distinctive square-sided arrangement with its wide corners was developed and patented in the early 1900s by Joseph Asscher. The patent has long since expired and the shape is now referred to in lab reports as a "square cut emerald".
The symmetry of the cut gives it a unique charm. The X-shaped facial pattern running from the corners to the hood is often referred to as a "windmill".
Emerald cuts and clarity
The face pattern of an emerald cut is particularly revealing of any inclusions that may be present in the diamond. Brilliant style veneer arrangements that promote rapid flashing tend to camouflage inclusions, particularly around the crown. The emerald cut with the relatively large table surface acting as a window and the slow-flickering long-pitch facets make the inclusions relatively easy to see. This is why you tend to see emerald cuts in the highest clarity grades. Diamonds of lesser clarity are usually cut into other shapes that will better hide the inclusions. This factor tends to make emerald cuts more expensive than most other high-end shapes.
While many buyers looking for the best value will focus on Si clarity when purchasing rounds, it is likely that value buyers looking for an emerald cut should focus on the VS as a base.
Emerald cuts and colors
As the emerald cut does not have as much sparkle as a well-cut round one, it tends to show the body color more strongly. A gyrus returns almost all of the light entering the corona, and in a bright environment, the gyrus body color is overwhelmed by ambient light returning to the eye. Just as it shows inclusions more easily, an emerald cut tends to show the true color of the body. This color is also sometimes trapped and concentrated at the edges of the stone, depending on its proportions. This again means that emerald cuts tend to be made of a rougher color, increasing the likelihood that a proper emerald cut will be more expensive, although the price per carat is generally lower for non-round shapes, quality for quality.
While value buyers will generally find suitable diamonds in the lower near-colorless I-J range, those looking for emerald cuts should focus on the upper near-colorless G-H range.

Emerald-cut diamonds and lightweight performance
The staggered cut facet arrangement produces much less glare than brilliant style cuts such asdiamond hearts and arrows. The large horizontal facets of the emerald cut produce long, relatively slow flashes rather than the shorter, faster flashes of brilliant styles.
Despite not being as sparkling, a well-cut emerald cut produces intense white flashes and colorful flashes (fire) that are impressive. Overall, the slower, bolder visual effects of the emerald cut appeal to many as more sophisticated than the frenzied glow that reveals itself from a brilliant cut. The emerald cut has a very distinctive flavor and, for some people, is the ultimate in diamond beauty.
Emerald and ASET cuts
OAngular spectrum evaluation tool(ASET) developed by the American Gem Society Laboratories (AGSL) provides a graphical view of light performance that can be used with any diamond shape. It reveals aspects of the quantity and quality of light that a diamond returns to the eye. While the types of images developed by ASET are well understood in brilliant-cut diamonds and, to a lesser extent, in other shapes with brilliant facet arrangements, the accurate interpretation of ASET signatures in emerald diamonds requires more experience.
Below are three sets of images for emerald cuts. from left to right ASET, Diamond Image and IdealScope . All three are very fine diamonds, but ASET signatures show significant differences in their light performance. One has a light leak problem, another has too much concentrated contrast, and the third has good visual balance. Learning to interpret ASET images for sophisticated shapes is an important resource for diamond buyers looking for the most beautiful diamonds.
Ideal Emerald Cut - AGSL Light Performance Cut Rating
AGSL has developed the most sophisticated scientific method to assess cut quality. from themsystem based on luminous efficiencyinvolves computerized ray tracing of 30,000 virtual light rays on a 3D model of the diamond to measure brightness, fire, contrast and light leakage. Diamonds that have the ideal amount of each factor receive an Ideal cut score.
Although most emerald diamonds on the market have GIA lab reports, they do not include an overall grade of cut because a GIA cut grading system for fancy shapes has not yet been developed. Only GIA reports for round diamonds come with an overall cut. For more information on the differences between these two top gemstone labs, check out our article onAGS x GIA.
As making emerald cuts for optimal light output requires more skill, time and experience, most manufacturers have decided that it is uneconomical to cut to ideal parameters given the relatively small market for the shape. This could change over time as more consumers realize the importance of cut quality.
Below is an example of a rating report based on AGS Platinum light output for an Ideal Emerald Cut. As with all Platinum reports from AGS Laboratories, the document features an accurate computer-generated ASET light map of the diamond.

Price of Emerald Cut Diamond
the basis fordiamond pricesis Rapaport's weekly list. Manufacturers and dealers use this guide as a starting point for commercial prices, which determine retail prices. There are two listings, one for rounds which are usually higher priced and the "pear shaped" listing that all fancy shapes are based on. List pears are smaller per carat than rounds by a significant margin. Typically, using a non-round shape is a way to get more diamonds for less money. But, as we have seen, there are characteristics inherent to emerald cuts that tend to prevent finding them for large savings. In general, you should increase color and clarity with an emerald cut than would be acceptable in the round.

Emerald Cut vs Diamonds Princess Cut
The two most popular straight diamond shapes are the emerald and theprincess cut. Though they share some shape traits, the look couldn't be more different. As we have seen, the emerald cut is a step design while the princess cut is a sparkly style. The princess pavilion has main faces that are vertical along with chevron corner faces. This creates a kind of sparkle and shine similar to round glitter, only with a square outline. The emerald cut, on the other hand, has longitudinal steps on the pavilion and crown that produce long, wide sparkles. Princess glitter patterns feature quick little flashes. The emerald cut has an understated, relaxing elegance, while the princess is a high-frequency flash bomb by comparison.
Do emerald cuts appear larger than other shapes?
Buyers are often interested in getting as much of a look as possible for their budget. While emerald cuts are theoretically less expensive than round cuts, the need to maintain higher color ranges and sharpness tends to negate the savings. Meaning, you'll likely need to aim for a slightly smaller diamond for a given budget. However, they tend to look a little bigger due to the length-to-width ratio. An emerald diamond ring can give more coverage to the fingers as the diamond extends further down the finger.
The ratio of an emerald cut can also determine whether the diamond is "set" with a good surface for its weight. You can find them with relatively flat crowns and shallow settings that will maximize the outer dimensions of the diamond. However, there is an optical cost to cutting any diamond too fine. This will result in loss of light recoil and/or fire.
If you are purchasing an emerald diamond, it is highly recommended that you work with a dealer who specializes in cut quality and who can provide thorough assessments, including advanced light performance diagnostics that demonstrate the light handling properties of the diamond you are considering. .

Length, Width & Depth
Ritani's gemologists recommend that the best ratio for emerald cut diamonds is 1.45 to 1.55, although some people prefer longer, thinner cuts (around 1.6), and some prefer the shorter, squarer cuts (around 1.3). The diamond's total depth percentage will also affect how much light it reflects.
Most emerald cut diamonds have length to width ratios ranging from 1.30 to 1.50. A ratio of 1.40 is considered “ideal”. However, ratios are dependent on personal preference. A lower ratio should be chosen for a more square shape, while for an elongated, more rectangular shape, a higher ratio is best.
