Walk into any jewellery store and you will see stones cut in dozens of different shapes: round, square, pear-shaped, every variation in between. But these are not just random design choices. Each cut serves a specific purpose, maximising brilliance, minimising flaws or showcasing the stone's natural colour.
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. The same cuts that define fine gemstone jewellery also appear across precision-cut crystal categories: Swarovski chatons, fancy stones and cubic zirconia all use the same classic cut geometries adapted for craft, costume and jewellery-making applications.
Here are the seven cuts you will 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 is no culet) arranged in a specific pattern designed to maximise 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 geometry is the foundation of crystal cutting too. Our Swarovski chatons collection uses round brilliant faceting in pointed-back form, and the Xirius cut introduced in recent years pushes the precision standard further with additional facets for enhanced brilliance.
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 and fine jewellery.
Like the round brilliant, the princess cut has tons of facets, usually between 50 and 58, creating lots of sparkle. But because it is 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 are also vulnerable to chipping, especially in softer gemstones. Most jewellers 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 are 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 colour. The large, open facets showcase the stone's colour and clarity without much sparkle to distract from it. But this also means flaws are way more visible: you cannot hide inclusions in an emerald cut.
The emerald cut has a vintage, Art Deco vibe that is currently having a major moment. Celebrities have been choosing emerald cut engagement rings lately, driving renewed interest in this classic style.
Because there is less sparkle, emerald cuts are often used for coloured gemstones where you want to appreciate the actual colour: sapphires, aquamarines, morganites. The cut does not compete with the stone's natural beauty. The same logic applies to crystal fancy stones, where the emerald cut profile delivers clean, architectural sparkle in designs that prioritise colour clarity over flash.
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 colour saturation. The cut's large facets showcase colour beautifully while still providing decent sparkle. Sapphires, rubies, and coloured diamonds look stunning in cushion cuts, and the cushion silhouette is a staple of the precision-cut crystal fancy stones range too.
The rounded corners make cushion cuts more durable than princess cuts, less vulnerable to chipping. Browse our Swarovski round and fancy stones collection for the full range of brilliant and step-cut shapes including cushion silhouettes.
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 maximise 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 centre of the stone that resembles a bow tie. Not all oval cuts have this, and skilled cutting can minimise it, but it is 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 coloured gemstones. The elongated shape and brilliant faceting showcase colour while still providing that sparkly appeal most people want in fine jewellery.
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 is distinctive without being too unusual.
Pear cuts are incredibly popular for pendants and earrings where the pointed end can face downward. In rings, they are 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 is vulnerable to chipping if it is not properly secured in a protective prong or bezel.
Colour distribution in pear cuts can be tricky. Sometimes colour concentrates at the point or appears uneven between the rounded and pointed ends. This matters more for coloured gemstones than for colourless diamonds, but it is 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 signals Art Deco elegance.
Like emerald cuts, Asscher cuts require high clarity gemstones. The large, open facets showcase everything, including flaws. But when you have a clean stone, the Asscher cut creates a mesmerising optical effect with depth and dimension.
Asscher cuts fell out of fashion for decades but have experienced a major resurgence. Vintage-inspired jewellery 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 jewellery 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. This principle applies equally to precision-cut crystals, where the precision and consistency of the cut directly determines the brilliance you get in the finished piece.
Cuts in Cubic Zirconia and Crystal Stones
The same seven cuts dominate the cubic zirconia and crystal fancy stones categories that jewellery makers and designers rely on for accessible-luxury pieces. Cubic zirconia in particular has become a staple for jewellers who want diamond-quality cut precision without the diamond price tag.
Our Swarovski cubic zirconia collection offers all the major cut geometries (round brilliant, princess, emerald, oval, pear, cushion) in jewellery-grade quality, manufactured to the same precision standards as Swarovski's crystal range. For a deeper understanding of how cut precision, glass clarity and foiling quality interact to produce brilliance, see our guide to why crystal quality varies.
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 stone 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. For manufactured crystals and cubic zirconia, durability is consistent across cuts, so your choice is primarily aesthetic.
Your application matters too. Active hands that will bump into things constantly? Probably avoid cuts with exposed corners. Jewellery that will see lighter use? You have more freedom to choose based purely on aesthetics. For brand selection guidance across the four-tier framework we stock, see our guide to comparing premium crystal brands.
FAQs
Which gemstone cut produces the most sparkle?
The round brilliant cut with its 58 facets is mathematically designed for maximum light return, producing the most sparkle of any cut. Cushion cuts come second with their brilliant-style faceting and softer light play.
Which cuts work best for coloured gemstones?
Emerald, Asscher and cushion cuts showcase colour best because their larger facets allow the eye to appreciate the stone's saturation rather than focusing on sparkle. Oval and pear cuts work well too for coloured stones where you want a balance of colour and brilliance.
Are these gemstone cuts also used in crystal fancy stones and cubic zirconia?
Yes. The same classic cut geometries (round brilliant, princess, emerald, cushion, oval, pear and Asscher) are used across the precision-cut crystal fancy stones and cubic zirconia categories, applied with the same mathematical precision as fine jewellery cuts.
Which cuts are most vulnerable to chipping?
Princess cuts have sharp corners that are vulnerable to chipping, especially in softer stones. Pear cuts have a pointed end that requires careful setting. Oval, cushion and round cuts are more durable due to their rounded edges.
Does cut quality matter more than carat weight?
Yes. A well-cut smaller stone will outshine a poorly cut larger one. Cut precision determines how much light the stone returns, which directly affects perceived brilliance and quality regardless of size.
What is the "bow-tie effect" in oval and pear cuts?
The bow-tie effect is a dark area across the centre of the stone that resembles a bow tie. It is caused by light leakage during cutting and can be minimised by skilled cutters. Examine oval and pear cut stones from multiple angles before buying to check how pronounced the effect is.
