Walk into any jewelry store and you'll see gemstones cut in dozens of different shapes - round, square, pear-shaped, you name it. But these aren't just random design choices. Each cut serves a specific purpose, maximizing brilliance, minimizing flaws, or showcasing the stone's natural color.
Some cuts have been around for centuries, refined over generations of gem cutters. Others are relatively modern innovations, designed to get the most sparkle possible out of a stone. Whether you're buying an engagement ring, designing custom jewelry, or working with durable crystal options for fashion projects, understanding popular cuts helps you make better choices.
So let's look at the seven cuts you'll encounter most often and what makes each one special.
Round Brilliant Cut
This is the most popular gemstone cut in the world, and for good reason. The round brilliant cut has 58 facets (sometimes 57 if there's no culet) arranged in a specific pattern designed to maximize light return. Light enters the stone, bounces around inside, and exits back through the top - creating that signature sparkle.
Originally developed for diamonds in the early 20th century, the round brilliant cut works beautifully for other gemstones too. Sapphires, rubies, and even softer stones like topaz benefit from this cutting style. The symmetry and proportions are mathematically calculated to create optimal brilliance.
The downside? You lose a lot of rough material when cutting a round brilliant. That waste drives up the price. But the end result - a stone that catches light from every angle - is worth it for most people.
Round brilliant cuts are incredibly versatile. They work in solitaire settings, halos, three-stone rings, earrings, pendants, you name it. If you want maximum sparkle and don't care about being unique, this is your cut.
Princess Cut
The princess cut is the square (or rectangular) answer to the round brilliant. It was developed in the 1960s and quickly became the second most popular cut for engagement rings.
Like the round brilliant, the princess cut has tons of facets - usually between 50 and 58 - creating lots of sparkle. But because it's square, you waste less rough material during cutting.
This makes princess cut stones slightly more affordable than round brilliant cuts of the same carat weight.
The sharp corners are both a pro and a con. They create a modern, geometric look that plenty of people love. But they're also vulnerable to chipping, especially in softer gemstones. Most jewelers recommend protective prong settings for princess cut stones.
Princess cuts work particularly well for gemstones with good clarity. Because of how light moves through the stone, inclusions are more visible than they would be in some other cuts. If you're going with a princess cut, you want a clean stone.
Emerald Cut
The emerald cut is all about elegance and clarity. Unlike brilliant cuts with their dozens of sparkly facets, the emerald cut has long, rectangular facets arranged in steps. This creates a "hall of mirrors" effect rather than a brilliant sparkle.
Originally developed specifically for emeralds (hence the name), this cut works beautifully for any gemstone with good clarity and strong color. The large, open facets showcase the stone's color and clarity without much sparkle to distract from it. But this also means flaws are way more visible - you can't hide inclusions in an emerald cut.
The emerald cut has a vintage, Art Deco vibe that's currently having a major moment. Celebrities have been choosing emerald cut engagement rings lately, driving renewed interest in this classic style.
Because there's less sparkle, emerald cuts are often used for colored gemstones where you want to appreciate the actual color - sapphires, aquamarines, morganites. The cut doesn't compete with the stone's natural beauty.
Cushion Cut
Cushion cuts have been around for over 200 years, though modern versions look quite different from their antique predecessors. The name comes from the shape - rounded corners and curved sides that resemble a cushion or pillow.
There are actually several variations of cushion cuts. Some have larger facets (similar to emerald cuts), others have brilliant-style faceting for more sparkle. Modern cushion cuts often have a "crushed ice" appearance with tons of small facets creating diffused sparkle rather than the sharp flashes you get from round brilliants.
Cushion cuts work particularly well for gemstones with strong color saturation. The cut's large facets showcase color beautifully while still providing decent sparkle. Sapphires, rubies, and colored diamonds look stunning in cushion cuts.
The rounded corners make cushion cuts more durable than princess cuts - less vulnerable to chipping. This is especially important for unique crystal cuts used in jewelry that'll see regular wear.
Oval Cut
Oval cuts give you the brilliance of a round stone with a more elongated, flattering shape. The faceting is similar to round brilliants - designed to maximize light return - but the oval shape creates the illusion of larger size and can make fingers look longer and more slender.
Developed in the 1960s, oval cuts have surged in popularity recently. They offer something a bit different from the standard round brilliant without being too unconventional. You still get plenty of sparkle, but the shape stands out.
One quirk of oval cuts is something called the "bow-tie effect" - a dark area across the center of the stone that resembles a bow tie. Not all oval cuts have this, and skilled cutting can minimize it, but it's something to watch for. In person, examine the stone from different angles to see how pronounced the bow-tie is.
Oval cuts work beautifully for colored gemstones. The elongated shape and brilliant faceting showcase color while still providing that sparkly appeal most people want in fine jewelry.
Pear Cut
The pear cut (also called teardrop) combines the best features of round and marquise cuts. One rounded end, one pointed end, brilliant-style faceting throughout. It's distinctive without being too unusual.
Pear cuts are incredibly popular for pendants and earrings where the pointed end can face downward. In rings, they're often worn with the point facing toward the fingertip, creating a lengthening effect.
Like oval cuts, pear cuts can suffer from bow-tie effects. They also require careful setting to protect the pointed end - it's vulnerable to chipping if it's not properly secured in a protective prong or bezel.
Color distribution in pear cuts can be tricky. Sometimes color concentrates at the point or appears uneven between the rounded and pointed ends. This matters more for colored gemstones than for colorless diamonds, but it's worth examining before purchasing.
Asscher Cut
The Asscher cut is essentially a square emerald cut - stepped facets, open corners, that same hall-of-mirrors effect. Developed in 1902 by the Asscher Brothers, this cut screams Art Deco elegance.
Like emerald cuts, Asscher cuts require high clarity gemstones. The large, open facets showcase everything - including flaws. But when you've got a clean stone, the Asscher cut creates a mesmerizing optical effect with depth and dimension.
Asscher cuts fell out of fashion for decades but have experienced a major resurgence. Vintage-inspired jewelry designs have brought renewed attention to this distinctive cut, and plenty of modern gem cutters are now producing Asscher cut stones.
The symmetry of Asscher cuts is incredibly precise - everything needs to be perfectly aligned or the optical effect falls apart. This requires serious skill from the cutter and adds to the cost, but the result is worth it for anyone who loves geometric, architectural jewelry designs.
According to the Gemological Institute of America, cut quality matters more than carat weight for a stone's overall appearance and value - a well-cut smaller stone will outshine a poorly cut larger one every time.
Choosing the Right Cut
The "best" cut depends entirely on what you value. Want maximum sparkle? Round brilliant or cushion. Prefer understated elegance? Emerald or Asscher. Looking for something that makes fingers look longer? Oval or pear.
Also consider the gemstone itself. Harder stones like diamonds, sapphires, and rubies can handle any cut. Softer gemstones might be better suited to cuts without vulnerable points - round, oval, or cushion rather than princess or pear.
Your lifestyle matters too. Active hands that'll bump into things constantly? Probably avoid cuts with exposed corners. Desk job where your ring won't see much abuse? You've got more freedom to choose based purely on aesthetics.
The Bottom Line
These seven cuts dominate the market because they work. They've been refined over decades (sometimes centuries) to maximize light performance, showcase color, or create specific aesthetic effects.
Round brilliant reigns supreme for sparkle. Princess offers a modern, geometric alternative. Emerald and Asscher provide vintage elegance. Cushion and oval deliver brilliant performance with distinctive shapes. Pear brings something unique to the table.
Your choice ultimately comes down to personal preference, the specific gemstone, and how you plan to wear it. But now you know what makes each cut special - and why some command higher prices than others.
