What Diamond Shape Should I Buy?

If you decide to purchase a diamond to be set into jewelry you’ll need to find a shape that really resonates with you. There are 10  popular shapes of diamond that you want to consider, and finding the right one for the ring or piece of jewelry you are inevitably going to have the diamond put into can be a bit of a tall task.

Using the inside information below, however, you’ll be able to better decide which shape you want your diamond to be cut into. Obviously, you’ll still want to pay attention to color, clarity, and carat weight, but the cut of your diamond is going to make or break its brilliance and its “stopping power” from a visual standpoint. Let’s highlight the most popular diamond shapes that you might consider in this quick guide!

Round Shape

Far and away the most popular of all the diamond shapes and diamond cuts today, a round diamond cut represents nearly 75% of all diamonds sold on the market every year. This is a beautiful cut for a ring, for earrings, for necklaces, and for most any other piece of jewelry imaginable. It is one of the most versatile cuts you will come across and that’s why it is so popular.

Another reason that round diamonds are so popular is because of the natural reflection of the light that occurs inside of a round diamond when it is cut appropriately. Light will enter into the diamond, bounce around and reflect throughout each of the cuts individually and help the diamond really glow coming and you won’t have to worry about any “lopsided illumination” the way you might have if you chose to go with a more exotic or fancy or shape.

Princess Cut Diamonds

Another of the more popular diamond cuts, especially when it comes to engagement rings these days, this cut has really only existed since the 1980s and is a tremendously of healing cut from a visual standpoint.

Princess cut diamond are more squared off the round diamond, but have the same kind of diagonal cuts at the bottom of the diamond to really reflect light throughout the stone itself. This is one of the more flexible fancy cuts you can shop around for, and its flexibility makes it a really attractive option for those looking to add this diamond to a ring, earrings, or something else entirely.

Cushion Cut Diamonds

Combining a square cut with rounded corners (and looking quite a bit like a pillow), this very classic, very elegant, and very timeless cut has been in existence for more than 200 years and was considered the most popular diamond shape up until right around the 1960s or so.

These diamonds look very substantial, have a pretty reasonable surface area, and reflect a tremendous amount of light that really brings them to life no matter what they have been set into. Refinements in the cut in recent years have made this more popular, and it’s really starting to trend upwards in the jewelry design world today.

Emerald Cut Diamonds

Mimicking the cut that almost all emeralds enjoy to bring out the lighting features that those stones are able to bring to the table, Emerald cut diamonds aren’t going to have the same kind of sparkle that a “brilliant style cut” offers but will instead have a hall of mirrors affect which will play with light and dark elements to create something really spectacular.

These kinds of diamonds are very popular when they are larger and set into necklaces or bracelets, but when placed into a ring they kind of lose a lot of the theater that they enjoy when the cut is matched to a larger diamond.

Asscher Cut Diamonds

Really popularize in 1902 by the Asscher Brothers of Holland, this diamond cut is very similar to the emerald cut but is more square in shape and has larger step facets, a larger crown, and a smaller “table”. All of these elements allow Asher cut diamonds to have more brilliance compared to the now traditional Emerald cut style, which makes this cut a popular compromise for those that want the overall shape of an emerald cut but would love the light play a more brilliant cut brings to the table.

Marquise Cut Diamonds

Again, we’re talking about a modified “brilliant cut” diamond, but it’s a lot longer and a lot more narrow than the diamonds that you are going to find any round and oval shapes.

This diamond has some very distinct features, some very distinct angles, and a football shape to it that allows for extreme luminosity and real fire and brilliance – but it’s going to lose quite a bit in the depth department unless you step up to a heavier carat weight than you were probably looking into.

As far as surface area is concerned, you’d have a really tough time finding anything that “delivers the goods” any more than a Marquise cut diamonds. If you’re looking to maximize the visual impact of the diamond you are having set into jewelry, this is the direction you want to go in.


Oval Cut Diamonds

Very similar to a round diamond (essentially a modified brilliant cut” diamond), oval diamonds have a similar fire and brilliance about them but also have an elongated shape that makes smaller diamonds with a lower carat weight look considerably larger just because of the optics.

Round diamonds inevitably look a little bit smaller because of the way that they are cut (though they make up for it when it comes to brilliance), but oval diamonds deliver all of that brilliance and all of that luminosity while still looking considerably larger – and more expensive – without customers having to spend a small fortune along the way. It’s possible to get a less than 1 carat diamond that looks like a 1.5 carat diamond at a fraction of the price when you go with the oval cut!

Radiant Cut Diamonds

The first ever rectangular cut to have a complete brilliant cut facet pattern applied to both the crown and the pavilion of this diamond, there may not be anything else available on the market quite like a radiant cut diamond.

Visually stunning, with plenty of heft to and weight to it, this is a cut best suited to diamonds that are slightly larger in size and it really plays nicely when set into an engagement ring (or any kind of ring, really) as well as when it is featured on a necklace.

Heart-Shaped Diamonds

Heart-shaped diamonds have become enormously popular in just the last few decades, symbolizing love, passion, and helping those looking to purchase diamond jewelry find something that really conveys their feelings to the person that they are buying the jewelry for.

Because of the complexity of the cuts, a lot of people are under the impression that heart-shaped diamonds are absurdly expensive or out of reach for those that are looking to buy diamond jewelry on a bit of a budget. Nothing could be further from the truth.

For the most part, larger diamonds are used in a heart-shaped configuration (anything smaller than half a carat weight really has the heart shape lost on it), but because of the numerous cuts made to the diamond stones with more flaws and those that are less than picture-perfect can be used without any degradation in the overall look of the finished product.

This makes heart-shaped diamonds relatively inexpensive compared to other carat weight diamonds cut in a different fashion and also makes jewelry that leverages heart-shaped diamonds very popular for those sticking to a budget!

Pear Cut Diamonds

A bit of a hybrid cut, with a round cut on one end of the diamond and a Marquise style cut at the other, this is a bit of a difficult diamond cut to pull off successfully – which makes it a little bit more expensive and a little bit fancier at the same time.

Ideally, the cut should be perfectly symmetrical from one side to another and the “shoulders and wings” should provide for beautiful and elegant curves. This requires the deft hand of an accomplished diamond cutter, however, making these diamonds pretty expensive.
