When it comes to choosing a diamond, the cut is one of the most important decisions you'll make. Diamond cuts refer to how a diamond is shaped and polished, impacting its appearance and how well it reflects light. It defines the stone's proportions, symmetry, and value.
A well-cut diamond will shine brightly, while a poorly cut one will appear dull, regardless of its qualities like carat weight or clarity. There are different diamond cuts: round, oval, pear, marquise, trillion, emerald, princess, and mixed.
Among all of these, the two popular options are the emerald cut and the princess cut, each known for its unique characteristics and stunning appearance.
- The emerald cut gives more elegant flashes, an elongated shape, and a clear view of the diamond.
- While a princess cut offers stronger brilliance, a square outline, and a more energetic sparkle.
Want an engagement ring or a special diamond jewelry gift? The better choice depends on what you want to see when you look at your ring. Your budget, clarity preference, setting, and daily wear also matter.
What is an Emerald Cut Diamond?
An emerald cut diamond has a rectangular outline with cropped corners and long, straight step-cut facets. The name comes from the cutting style first used for emerald gemstones, where the cut helped reduce stress on the stone.
Today, the emerald cut is strongly associated with diamonds and engagement rings.
Its beauty isn't based on maximum sparkle. Instead, it creates broad reflections that can look like long mirrors inside the stone.
What is a Princess Cut Diamond?
A princess cut is usually square or slightly rectangular and uses a brilliant-cut facet pattern. GIA describes it as a square modified brilliant, although princess diamonds can have rectangular outlines too.
The shape became popular as a modern alternative to round brilliant diamonds. Its square outline gives an engagement ring a crisp, geometric look without giving up the sparkle many buyers want.
GIA also points out that princess cuts can have different pavilion and facet arrangements, so two stones with the same carat weight can show noticeably different patterns of sparkle.
Emerald Cut vs Princess Cut Diamond at a Glance
| Feature | Emerald Cut | Princess Cut |
| Shape | Rectangular | Square or slightly rectangular |
| Faceting | Step cut | Brilliant cut |
| Light effect | Broad flashes | Strong sparkle and fire |
| Color visibility | Higher | Lower |
| Corners | Cropped | Sharp |
| Style | Elegant and architectural | Modern and geometric |
| Clarity visibility | Higher | Lower |
| Best for | Clean lines and subtle brilliance | Maximum sparkle |
GIA explains that step cuts use larger, broader facets that create a hall-of-mirrors effect, while brilliant cuts use smaller facets to create more brilliance and fire.
1. Visual Appeal and Style
Shape and design are the most apparent differences between emerald cut and princess cut diamonds.
The emerald cut is rectangular, with large, flat facets and cropped corners. It's a step-cut diamond, which has the diamond facets arranged in parallel rows with the appearance of a staircase. The cut is clean, sleek, and has vintage and Art Deco connections to its clean lines.
The princess cut is square or slightly rectangular and has sharp, well-defined corners. It is a brilliant cut, as it's designed with many small facets that reflect and refract light to the greatest extent, unlike the emerald cut. It has a modern and geometric appearance due to its square shape.
Compared to the emerald cut, this cut tends to have more facets, ranging from about 58-76 facets, which gives it more brilliance and glitz.
2. Performance in Light
When choosing a diamond, one of the most important factors is brilliance. The brilliance of a diamond is mostly determined by the way light reflects off it and its cut.
A step cut diamond will have a "hall of mirrors" effect due to the cut of the facets. It has a characteristic of flashes of light and dark bands instead of the sparkle or fire of other cuts. Adds a refined level of sparkle but not as much as a princess cut.
A princess cut diamond is known for its dazzling brilliance. It is one of the most brilliant diamond shapes after the round brilliant cut. Its numerous facets allow it to reflect light from every angle, resulting in a bright, fiery sparkle. The intense light reflection gives the princess cut a much flashier look.
3. Clarity and Hidden Flaws Unveiled
Princess cuts are generally more forgiving of small inclusions.
Brilliant-cut facets create a busy pattern of reflected light. That can make minor inclusions harder to notice.
Emerald cuts are less forgiving.
Their large, open facets create clearer viewing areas across the stone. An inclusion sitting beneath the table can become much easier to see.
GIA recommends paying close attention to clarity and the location of inclusions when buying a diamond. Its guidance also notes that brilliant cuts can make inclusions harder to see than step cuts.
A well-chosen eye-clean diamond can make better sense than paying a premium for a grade that gives you no visible benefit.
For emerald cuts, though, inspect the actual diamond carefully. The clarity grade alone doesn't tell you how noticeable an inclusion will be.
4. Durability and Everyday Wearability
Both are diamonds, but durability isn't only about the hardness of the material. The shape and setting also matter.
Emerald cuts have cropped corners, which can reduce exposure at the vulnerable points.
Princess cuts have sharp corners. Those corners can be more susceptible to impact if they're left unprotected.
The quality of the individual diamond matters too. GIA advises buyers to pay attention to inclusions or fractures that reach vulnerable areas such as the girdle or tips because these can affect durability. For either shape, choose a secure setting and have the ring checked if the prongs become loose or damaged.
5. Visual Size Comparison Per Carat
The cut of a diamond also impacts how large the diamond appears.
An emerald cut diamond's shape is elongated and rectangular, which maximizes the illusion of a larger stone. The surface area, or face-up size, is larger than a round brilliant of the same carat weight. This implies that an emerald-shaped diamond may appear larger than its carat weight. This is perfect for anyone who wants to make it appear larger while keeping the carat count down.
The diamond shaped in a Princess Cut can be a bit smaller in carat size than an emerald cut of the same carat, depending on the specific proportions. This is because the princess cut is deeper, allowing more of the weight of the carat to be distributed in the lower part of the diamond - the pavilion - and not the visible top surface.
6. Pricing and Value
Diamond price depends on far more than shape. Carat weight, color, clarity, proportions, polish, symmetry, certification, and the quality of the individual stone all affect the price.
Princess cuts can make efficient use of rough diamonds, which has helped make the shape a popular choice for buyers seeking a square diamond with strong sparkle. GIA notes this efficiency as one reason princess cuts can be less expensive per carat than round brilliants.
Emerald cuts can require more attention to clarity because their open facets make inclusions easier to see.
So don't compare two diamonds only by price per carat. Compare what you're actually getting for the money.
A slightly smaller emerald cut with excellent clarity may suit you better than a larger stone that has distracting inclusions. The same principle applies to a princess cut with weak light performance.
Which Cut Is More Popular Right Now?
Emerald is rising, and princess is falling, and they have roughly converged.
Princess cuts peaked in the 1990s and 2000s, when they were the second most popular engagement ring shape after round. Their share has been declining steadily since, from around 12% of engagement rings to somewhere near 6 to 8% in recent industry surveys.
Emerald cuts have moved the other way, climbing from roughly 5% in 2020 to around 11%, driven by the same shift that pushed oval past round for the first time in a century. Buyers have moved toward elongated shapes that read larger face-up and photograph distinctively.
None of that should decide your purchase. A princess cut is not dated because fewer people choose it, and an emerald cut is not better because more do. But it does have two practical consequences worth knowing.
Selection is wider for emerald cuts right now, particularly in engagement rings and larger carat weights, simply because more are being cut and set.
And the setting dates a ring far more than the shape does. A princess cut in a clean solitaire or a protective V-prong reads as current. The same stone in a bulky double halo reads as 2008. If you love the square outline, the shape is not the problem.

What Length-to-Width Ratio Is Best?
The length-to-width ratio tells you how elongated a diamond looks. You calculate it by dividing the length by the width.
GIA describes this ratio as an important way to understand the outline of fancy-shaped diamonds. It also notes that preferred ratios can vary based on consumer taste and cutting considerations.
Emerald Cut Length-to-Width Ratio
A ratio around 1.30 to 1.50 is a useful starting range for shoppers who want a classic elongated emerald shape.
A lower ratio will give a broader, flatter appearance. The higher the ratio, the longer and narrower the appearance. There is no "magic number". Although two emeralds may have the same ratio, they still may appear different due to the proportions, placement of facets, and size of the stones. Before making your choice, check the stone itself.
Princess Cut Length-to-Width Ratio
The ratio of 1.00 to 1.05 is pretty close to a square. The higher it gets, the more rectangular the stone looks. Useful when you want to try to match a princess center stone for a certain ring design. Small differences in proportions may be more apparent in the setting.
