Round Brilliant Cut Diamonds

Round brilliant cuts are by far the most popular shape of gem, the round diamond is the first thing that may come to mind when envisioning a classic diamond engagement ring.

Whether it's a large circular stone or a petite gem, the round diamond is sure to captivate all who see it. Round diamonds are the most expensive per carat because of their brilliance and popularity (i.e demand) and because during the polishing process into round brilliants there is a lot of "waste".

There are many reasons why this shape makes up such a significant portion of the diamonds sold. For starters, it's classic and timeless. Aside from that, it's also the easiest shape to cut without harming the stone's clarity. Two round diamonds can be cut without losing much of the crystal in the process, which can't be said for many of the other shapes.

Oval Cut Diamond

Oval Cut Diamonds

A slight variation on the classic round stone, the oval diamond is another one that exudes elegance and timeless style.

It can seem to extend the size of a smaller finger, and the diamond itself can appear to be larger than it actually is. The Gemological Institute of America doesn't grade oval diamonds for cut, so it's especially important to have a conversation with your jeweler to discuss the stone and make sure it offers optimal brilliance for its size and shape. He or she can also assist you in identifying the bowtie effect that this shape is susceptible to. While it can be invisible to the naked eye, professional inspection of the diamond can show a dark area that stretches across the center of the stone. It's present in all oval diamonds, but the degree to which it shows varies.

Princess Cut Diamonds

The next most popular diamond shape is the princess cut, which is square in appearance and offers a beautiful reflection of light. The perfect square shaped diamond!

In fact, it's the round and princess cut shapes that are the most brilliant, meaning that they can have more polished sides that seem to illuminate the stone. While the classic princess shape is square, there are some alterations that make it appear more rectangular. These rarer finds are actually less expensive per carat, and are sometimes preferred over the perfectly symmetrical four sides. Regardless of the exact measurements, it's crucial that this shape is set with four prongs to protect the corners and offer the appropriate amount of support to display the gem.

Cushion Cut Diamond

Cushion Cut Diamonds

Also known as pillow cut, the cushion cut diamond shape is somewhat of a variation of the princess shape.

Both have a square design, but the rounded corners of the cushion cut is what sets this shape apart from the rest. It's these rounded corners that also give it a softer romantic appeal. For exceptional dimensions, opt for a stone that's slightly more elongated, which will give you optimal brilliance and captivate the eye with its beauty. Several hundred years ago when this shape first came into existence, it was the most popular choice - much like the round stone is today. For those who value tradition, this is quite possibly the perfect shape to wear for a lifetime.

Radiant Cut Diamonds

To get the unique shape of an emerald or asscher cut without sacrificing brilliance, opt for the radiant diamond.

It comes in either square or rectangular shape and multi dimensions makes this the perfect in between for those who want something sparkly and different. When choosing a gem of this shape, it's important to check for the bowtie effect that can be present in the middle of the diamond. Talk to your jeweler to make sure you're getting a high quality stone that offers relentless shine and beauty.

Pear Shaped Diamond

Pear Shaped Diamonds

If you're having trouble deciding between the classic characteristics of an oval cut diamond and the striking style of the marquise, a pear shape might be the perfect option for you.

Much like the name implies, the stone resembles that of a pear, with one end rounded and the other coming together at a point. The most valuable pear shaped diamonds have symmetry throughout. Look for the oval end to have a perfectly rounded edge, and make sure the pointed end lines up exactly across from the center of the oval. As with the oval cut, there is a chance that the bowtie effect could be visible. Check to make sure that it's not present to the naked eye before deciding on the stone.

Emerald Cut Diamonds

Originally created for the cutting of emeralds, the shape is a less common but glamorous choice for a diamond.

The pavilion in emerald cut diamonds and the step-cut polishing style are sculpted to draw the eye to the table of the gem and highlight its clarity. For this reason, it's extremely important to opt for a high quality gem when selecting this shape. Its "hall of mirrors" effect makes it the perfect choice for someone who prefers elegance and clear beauty over sparkly, brilliant stones.

Marquise Diamond

Marquise Cut Diamonds

The marquise diamond is less common than many of the others, but it offers a rare stone the opportunity to be even more special for the woman who wears it.

A long stone with two pointed ends is characteristic of this shape, and is a beautiful choice for those with slender fingers who wish to draw more attention to them. Without a doubt, this bold shape will grab the attention of all who take a look. Much like the oval diamond, the marquise's narrow cut can cause the gem to appear larger than it truly is, which further supports its bold, striking beauty. This is the shape for those who like to steal the show and have all eyes on them. In fact, the shape was created at the order of a king who sought a diamond that best matched his self-proclaimed "perfectly shaped mouth."

Heart Shaped Diamonds

When you present a woman with a heart diamond, you're expressing to her that she will forever carry a part of you wherever she goes.

With this shape, it's essential to choose a stone that's both symmetrical and larger than .50 carats. Anything smaller than that may make it difficult to distinguish its design - though, this could be preferable for those looking for a more subtle shape. Be sure to look for a cut that offers the most brilliance to further draw attention to this beautiful, unique diamond.

Asscher Cut Diamond

Asscher Cut Diamonds

The asscher stone is another less common shape that produces a very unique look.

With a step-cut, much like the emerald, the asscher cut has a large table that makes it crucial to find a high clarity stone. While the emerald is rectangular in appearance, the asscher is more of a square shaped that, because of its other angles, can sometimes look like an octagon. The shape peaked in popularity in the 1920s when the Gatsby style was in effect, and you can almost envision the stone gracing the gloved finger of a classic flapper girl. Currently, it's gaining in popularity and helps pay homage to one of the most fashionable generations of all time.

Choosing the Right Shape

Much like there are certain hairstyles that work best with specific facial structures, there are diamond shapes that beautifully complement the characteristics of a person's finger. A hairstyle can grow back, but a diamond is an investment that lasts a lifetime. Be sure to consider not just how the diamond appears as you're holding it, but also how it looks on your hand.

Those with long, delicate fingers should opt for boxier shapes, like the princess, cushion or asscher, which will add width to the finger and make it appear shorter. Alternatively, shapes like the marquise and pear help lengthen the finger and make it appear more slender. Also, those with larger hands are able to beautifully display bolder shapes that may seem overpowering on a smaller hand. It's most flattering for petite frames to stick to shapes that don't cover as much of their fingers so the diamond appears proportional and fits in perfectly with the person wearing it. In cases like these, choose marquise or emerald, which will help draw attention to the beautiful stone without taking over the hand. It's important to keep all of this in mind when exploring the numerous possibilities for a diamond that will stay with you forever.
