Diamond Shapes

Diamond Fun Fact

Diamonds are formed under extreme heat and pressure deep within the earth’s crust, and come to the earth’s surface through volcanic eruptions that formed kimberlites and lamproites that host diamonds

The term 'Diamond Shapes' refers to the actual inherent shape of a diamond but is sometimes used to when referencing diamond cut. A Radiant cut and an Emerald cut share the same shape - a rectangle with trimmed edges, however their cuts are different which makes the 2 cuts very distinguishable from each other. Some shapes are traditionally cut using only one cut. One such example is the round diamond, which is always cut using a Brilliant Cut - so much that it is simply known as Round Brilliant.

With all this said, there are several diamond shapes that are popular today and make up the vast majority of diamonds that are used in jewelry. It is only when a raw diamond is cut into these shapes that the real beauty, shine and luster of a diamond comes out.

Round diamonds

Round Diamonds are the most popular of the diamond shape out there. A round brilliant, is what most people associate with round diamonds. This shape has been around for over a century, and has been researched and improved over the years. Today's know-how and technology can be used to achieve truly amazingly cut brilliant round diamonds.

Round Brilliant's popularity means that there are more rings for you to choose from, making it easier to find a ring design and a diamond that you like.

Princess diamonds

The princess shape, or princess cut, is square-shaped and cut similarly to a round brilliant. This gives it a fiery effect like a round brilliant diamond when looked from above. The princess shape has become very popular with diamond rings, and engagement rings. The square shape with pointed corners alongside its sparkle and fire characteristics make it a desirable shape.

Marquise diamonds

The Marquise shape is a good for making a diamond appear larger. Looking at diamonds of the same carat weight, the Marquise shaped diamond will usually appear larger than the others. It's also a good shape to keep in mind when for the center diamond of a 2 side-stones ring, because of its elongated shape.

Oval diamonds

The Oval shape is a brilliant cut, giving it the characteristic sparkle and fire you would expect. Like the Marquise shape, it has an elongated shape, which compliments long fingers, giving them a more slender look. It can also look great as a center diamond when accompanied by 2 side-stones.

Pear-shaped diamonds

The Pear shape, also known as the Teardrop shape has a unique unsymmetrical shape. Its special shape along with its brilliant cut its make it an appealing choice for engagement rings, mostly as a solitaire.

Emerald diamonds

Emerald diamonds are classic. These are step-cut diamonds, rectangular shaped with trimmed edges. They have high luster due to the large flat surface area and show off the beautiful properties of a very clear diamond - for those who are willing to appreciate it. Emeralds are not usually popular choices for engagement rings since the step-cut lacks the brilliancy and fire of the brilliant cut. This shape is more suited for old-fashioned looking prestigious jewelry.

Radiant diamonds

The Radiant cut is similar in shape to the Emerald - both are rectangular with trimmed edges. However, Radiant cut diamonds are not step-cut. The Pavilion bottom part of the diamond is cut using Brilliant cut facets, while the top part is a combination of step-cut and brilliant cut. Radiant cut looks very different than Emerald cut in that it has the brilliancy and fire that you would expect from a brilliant cut diamond. This cut might be an option to consider for engagement rings as a center stone.

Heart diamonds

The Heart shape is cut in brilliant cut fashion which gives it fire, brilliancy and scintillation. When choosing a heart shaped diamond it's important to look at the symmetry of the stone. If the stone does not have good symmetry, the stone will perform poorly under many light conditions. The table must be centered and not favoring a specific side. Try to vision imaginary lines across and along the stone and see that both sides are symmetrical.

Asscher diamonds

The Asscher cut is a step-cut very similar to the Emerald cut, only it is square-shaped do to its length to width ratio. Like step-cuts it has a classic old fashioned look with great luster coming off the flat planes of the diamond. When choosing an Asscher cut make sure that no inclusion are visible through the table since the step-cut makes these inclusion more visible when compared to brilliant cut.
