Diamond Shape

These days diamonds come in all shapes and sizes to suit everyone’s preferences. Some diamond shapes are considered outdated or old-fashioned while others remain timeless & classic. Round brilliant diamonds are the most popular shape of diamond and because of this they’re also the most common.

A brilliant round diamond will typically:

  • consist of 57 sides
  • be incredibly shiny
  • come with a heftier price tag than diamonds of other shapes

Round diamonds have been cut for decades, and despite technological advancements evening the playing field between it and other shapes, they remain massively popular & are considered classic. After round diamonds, princess, oval and cushion shaped diamonds are the most popular.

Thanks to scientific developments, the diamond world is being revolutionized by new technologies that enable us to produce diamonds with their light reflection capabilities as the main priority. This advantage means that new techniques have been developed and older techniques have been modernized, refined and scientifically enhanced. While there’s no denying that when it comes to its interaction with light, round diamonds are the perfect stones, many other shapes are now coming to light and rising in popularity.

Diamonds that feature any shape other than round are referred to as ‘fantasy diamonds’ and are much cheaper than round diamonds. Fantasy diamonds boast a range of different designs and this is a very important factor to be considered. Tear-drop diamonds, for instance, can either be long and narrow or short and fat & look completely different in different ways. On top of this, special attention needs to be paid to ensure that the diamond itself is relative when compared to its surface area and isn’t rubbery in shape.

In more times than not, when you purchase a fantasy diamond you won’t receive all the specific information relating to the diamond because these diamonds don’t have a cut grading. Because of this, you need to investigate all options of fantasy diamonds to ensure the one you pick is the right option.

We’ll be taking a look at the different shapes of diamonds, so you can make the right decision.

The Different Shapes of Fantasy Diamonds

Princess Diamonds

Since its inception in the 60s, princess diamonds have risen in popularity and today are considered the most popular fantasy diamond. Princess diamonds are square in shape and their sides possess equal lengths, resulting in a clean look. Sometimes a princess diamond will be shaped more to resemble a rectangle but this is not very common.

Because of its unique structure and low level of core material loss, princess diamonds retain a larger surface area than that of a round diamond and thus appear bigger.

Remember: Princess diamonds need to be inlayed in such a manner that the teeth holding the diamond rest at the very tips of the diamond.

The downside to princess diamonds is that they require an extremely specific inlay technique which often means the resulting jewelry can’t be customized.

Cushion Diamonds

Cushion diamonds are making a comeback! These are the diamonds you’ll often see gracing the pages of jewelry magazines and adorning the bodies of prevalent figures in the fashion world. For over two centuries cushion diamonds were the preferred diamond shape thanks to the sturdy and durable design. As you may have guessed, cushion diamonds are typically square or rectangle in shape with rounded edges that give the diamond its cushion-like appearance.

Cushion diamonds produce a fair amount of sparkle which, when combined with its vintage styling, makes it a stunning option for many. With vintage being very much back in fashion these days, cushion diamonds are once again rising in popularity.

Remember: Cushion diamonds will often have a wide girdle which diminishes their overall surface area.

Tear-drop Diamonds

As the name implies, Tear-drop diamonds are shaped to look like a tear drop. Tear-drop diamonds are a combination of round and marquise diamonds, which makes them quite unique. While their elegant shape makes Tear-drop diamonds perfect for usage in earrings and pendants, today we’re seeing more of these on rings.

This is because they tend to make the finger appear more delicate & slender. Bear in mind that with Tear-drop diamonds, the shoulders of these diamonds are round and not flat & the tip of the diamond should always be aligned with the mid-point of its shoulders.

Remember: Tear-drop diamonds tend to be more expensive than other fantasy diamonds because they require precision cutting to appear symmetrical.

Oval Diamonds

Oval diamonds are extremely popular because they mimic the look of a round diamond, minus the hefty price tag. Oval diamonds usually boast unique designs while preserving a high amount of sparkle, which is another reason why lovers of round diamonds opt for this shape.

These diamonds are oval in shape and feature a flat surface area which makes them seem bigger than they are. While this is impressive, it also means that the risk of a rubbery look is present, so a properly polished finish is of the utmost importance.

Remember: Oval diamonds are known to produce a fair amount of sparkle but, due to the common occurrence of bow-tie shapes appearing within the rock itself, can often result in a darker shading.

This darker shading caused by the bow-tie effect can either add a unique, moody feel to the rock or make it look gloomy and unappealing so always be on the lookout for this before you buy.

Marquise Diamonds

The story behind the Marquise diamond will appeal to the inner romantic part found in all of us. Rumor has it that this diamond shape was specifically designed in the 1800s by Louis XV as tribute to the almond shape of his lover’s, Madame de Pompadour, lips. To this day, this shape of diamond remains highly exclusive and is not a common shape. More often than not, Marquise diamonds appear large in size thanks to the elongated design.

The bow-tie effect is also found in this shape of diamond, so be sure to keep that in mind when buying.

Remember: The downside to this classy shape of diamond is that the tips are sharp which can easily result in damage, so always ensure that the stone’s edges are sealed off. Most often this is done with a light coating of gold.

Emerald Diamonds

Emerald diamonds are diamonds that have been shaped to look like the form of an emerald. Usually rectangle, but occasionally square, this diamond embodies elegance with a sassy dash of individualism. The emerald shape is achieved thanks to a step cut, as opposed to the side cut process that most diamonds undergo. This process results in a terraced feel rimming a large table.

In terms of how they look and the way they react with the surrounding light, this shape of diamond is unique when compared to more modern shapes. It remains popular thanks to its vintage feel.

Remember: this shape of diamond is not known for its shininess and it is tough to find one that is free from inclusions or blemishes. Aim for a high grade of clarity because in this shape of diamond, blemishes are easy to spot.

Asscher Diamonds

Asscher diamonds aren’t as common as other diamond shapes. Originating in 20th century Netherlands, this shape of diamond consists of a truly intriguing design. At a glance, Asscher diamonds are similar to emerald diamonds but upon closer inspection you’ll note that the table is smaller. The fundamental design elements, such as table size and step method, are the same.

It is difficult to get it right, which is why they are so rare. The incredible design appears as a square within a square within a square.

Remember: on top of the high level of craftsmanship that goes into producing this shape of diamond, the diamonds need to be of a high clarity to achieve the desired result. This means they can be expensive.  Finally, these diamonds need to be as close to a perfect square as possible in order to achieve the desired visual effect.

Radiant Diamonds

Radiant diamonds are square or rectangle in shape and are shaped similarly to the Emerald cut diamond. The main difference between the two is that radiant diamonds are created by use of the traditional side cut. Radiant diamonds were the first shape of diamond to be polished by means of modern radiant polish and are well loved for their vintage look.

Extremely popular, even in spite of its risk of containing the bow-tie effect, radiant diamonds are considered modern and safe to inlay. The vintage appeal combined with its modern design makes this a good choice for those looking for a rectangular ring of a more classic appearance.

Heart Diamonds

Heart diamonds are the result of cutting diamonds to rid them from inclusions in an attempt to boost their clarity.

Not very romantic, right?

Regardless, today this shape is sought after because it represents love and comes in many variations. Some heart shaped diamonds will feature a short and wider design while others will boast an elongated & narrow design.

Remember: when shopping for heart shaped diamonds nothing is more important than the overall symmetry of the rock.

Keep this in mind when choosing which variation of this shape you would like and ensure that whichever inlay you pick highlights the unique heart shape instead of hiding it. Heart diamonds are on the more expensive side because it is so difficult to achieve a symmetrical heart shape and cannot be done on smaller diamonds.

Triangle Diamonds

Triangle diamonds are a unique shape and definitely an acquired taste. People who pride themselves on standing out and being different are the perfect wearers of triangle diamonds. While they trend every now and again, triangle diamonds don’t fit into the industry norm. Usually, Triangle diamonds are used as side diamonds, framing either side of a round or oval diamond. The tips of Triangle diamonds are usually sharp but can be rounded too, depending on what look you’re after.

Remember: Most triangle diamonds have flat surfaces and generally appear bigger than other diamond shapes because of this.

Triangle diamonds are perfect for invisible inlays, where six smaller diamonds are connected to give the impression of one solid 2 carat diamond.

Are You Opting for a Fantasy Diamond? Keep the Following in Mind

Due to the expensive nature of round diamonds, many people opt instead for a fantasy diamond. When you’re looking at purchasing a fantasy diamond it’s important to keep the following in mind:

  • Surface area: Because of the complex crafting that goes into achieving certain shapes, the surface area of fantasy diamonds is often small.
  • The bigger the surface area, the bigger the rock looks and thus the more expensive it will be.

    A lot of the time, fantasy diamonds have a smaller surface area.

  • Variations: For all the different shapes of diamonds there are different variations of them.

    For example, a heart shaped diamond could be elongated and narrow, or wide and chunky and a tear-drop diamond can be long or short.

    What you purchase should fit your personal taste.

    Consider the layout and the diamond’s appeal.

  • Shop around: When you think you’ve found the perfect shape of diamond, it’s important to shop around and look at different models of this shape to make sure you select the right one for the right price.
