Anyone who loves diamonds knows about the 4 Cs - cut, clarity, color and carat. Most often though, when we think carat, we're imagining of the size of the diamond when it's really the weight of your diamond. So, when you think "the larger the diamond, the greater the carat weight", that's not necessarily true.

Allow us to illustrate our point. Take the 2ct diamond...if you looked at the rings below, which range from 1 to 3cts, which one would you suppose is the 2ct diamond ring?

Going by the logic of larger size means larger carat, the second picture is obviously the 2ct diamond (by now, you've clicked on the image and discovered that's not actually the case!). Which begs the question, if the diamond is the same size, why does it look so different from ring to ring?


How did you choose your 2ct diamond's cut?

We've always known that diamonds are cut to maximize the stone's clarity, color, brilliance and general appearance...but we rarely consider how your chosen cut is going to influence your diamond size. You and your friend may have bought 2ct diamonds, but your end result is very different. And we're going to tell you why.

At its most simplistic level, size is a matter of perception and appearance. So, although your diamonds may be the same weight, depending on the cut you choose, you may get to see more of it. As a general idea, squares shapes appear larger than rounds, and longer shapes like ovals, marquise, pear and emerald will seem larger than both.


Round Brilliant Cut

One of the most popular cuts for a diamond is the round brilliant cut. This diamond is cut in a cone shape and allows maximum light through its flat top (the table), which maximizes its brilliance. However, getting your rough diamond cut this way means that a lot of it goes to waste. By the time it's been cut and rounded out, you've got roughly only 50% of your original diamond. Expensive in more ways than one! Since you have a smaller surface to work with, the diamond weight lies in its depth, and this is how your final round 2ct diamond looks:

Princess Cut

A princess cut (also called the square modified brilliant) is also immensely popular, second to the round brilliant. In this cut, the table is square (occasionally rectangular), with the lower portion being an inverted pyramid with four beveled sides, which accentuates the crystal's fire and brilliance. Thanks to its shape, this cut wastes the least amount of the original rough diamond...retains 80%, in fact. So, with its larger surface, the princess cut has less depth but appears much larger!

Emerald Cut

The emerald cut is a popular step cut (the steps are in the pavilion) with a large, open table with truncated edges. This particular cut gives the diamond a fascinating play of light and dark, which coupled with its long, sleek lines gives it an overall elegant feel. This particular cut has a shallow pavilion and crown, which does actually create a larger table (so it's not just the appearance of being larger).

Very similar to the emerald cut is the Asscher cut, which is more square-shaped than the emerald cut. Also a style that highlight diamond clarity, it has larger step facets and a smaller table.


Cushion Cut

The cushion cut combines a square look with rounded edges, giving it the appearance of a pillow (which is why it's also called a cushion cut). While this cut lacks the brilliance of a round brilliant cut, it does however beautifully highlight the diamond's brilliance and clarity, and is the perfect setting for that antique feel. However, these diamonds tend to be cut to greater depth, leading to a smaller table and a smaller appearance.

Marquise Cut

A modified brilliant cut, the marquise diamond is shaped much like a football – long and narrow. This shape creates the illusion of greater size, thanks to its large crown surface area. This shape is the one to go for if you're looking to maximize the perceived size of your rock (there's also the added advantage of these shapes making your fingers look long and slim!).

Oval Cut

Like the marquise diamond, the oval cut is also a modified brilliant cut. With its similarity to the round brilliant, this cut also maximizes the diamond's fire and brilliance but has the added advantage of length, which once again creates the illusion of greater size over round and rectangular cuts. Plus, it also makes your fingers look longer and slimmer, much like the marquise.

Pear Cut

The pear-shaped diamond, a modified brilliant cut also called the teardrop, is a blend of the round and marquise cuts, visible in its one rounded side and one tapered point. As a blend of both, it has the characteristics of both – it highlights the brilliance of the diamond while simultaneously creating the illusion of a diamond larger than a round brilliant, thanks to its tapered point.

Radiant Cut

The radiant cut diamond, like the princess cut, has a brilliant cut facet pattern in the crown and pavilion. But from a purely appearance perspective, this cut is a mix of the elegance of the emerald cut and the brilliance of the round cut. This pattern does, however, focus the diamond weight in its depth, which renders its surface smaller in appearance.

These are a mere handful of all the different cuts available, but they're definitely the most popular. And now that you know all this, are you ever going to look at your diamond ring the same way again?
