When we talk about diamonds, we automatically think of a round gemstone. The round diamond, also called a brilliant, is undoubtedly the most famous of all diamond cuts. The oval diamond is a cut that bears many similarities to the brilliant. Like the brilliant, the oval diamond is also a popular choice for engagement rings and other jewellery. What makes the oval diamond so unique, and what should you pay attention to when choosing an oval diamond engagement ring? This article will teach you all about the oval cut.


What characterizes the oval diamond?

The oval diamond has an elongated shape, and is cut in as many facets as the brilliant, namely 57 or 58. As with other cuts, a so-called 'bow tie' effect can also occur with an oval diamond.

This effect can be recognized by the black spot that arises in the form of a bow, which prevents the light from being reflected properly. Even experts disagree on whether this effect, which can only be seen from a very close angle, is desired or not.

The appearance of the oval diamond

Because of its special cut, the oval diamond looks larger. Why? An oval diamond has a larger surface area than a brilliant of the same carats. For example, a 1 carat oval diamond appears about 10% larger than a round specimen with the same carat weight.

It's not only diamonds that are very pretty in the oval cut, but other gemstones are often oval cut too. This comes out best in an entourage ring or halo ring.

The history of the oval cut

Oval cut diamonds have existed for hundreds of years, but the modern cut did not appear until 1957. This was first performed by Russian diamond cutter Lazare Kaplan, who had learned the trade from his famous uncle, Abraham Tolkowsky. Kaplan became known for his sophisticated technique of splitting stones that until then were considered worthless, or by splitting diamonds with large inclusions in such a way that the smaller stones were eventually flawless. His big break, however, came with the oval cut, which still guarantees him a spot on the Olympus of diamond cutters.

Some of the world's most famous and exclusive engagement rings now carry Kaplan's design. Katie Holmes and Heidi Klum, among others, wear an oval diamond.

The difference between an oval diamond and a brilliant

Objectively, the brilliant radiates the most beautiful brilliance. However, an oval diamond hardly has to be inferior to this, as the cut has as many facets as a brilliant cut. An engagement ring with an oval diamond is perfect for women who love the brilliance of a round diamond, but like to show off a slightly more unique ring.

What to look out for when purchasing an oval diamond

The ratio between length and width varies with oval diamonds. A good guide value, depending on the type of ring, is a ratio of 1.35 to 1.50, width and length, respectively. However, you can also buy a diamond with custom proportions to enhance its character. Greater length makes the diamond sharp and pronounced. For example, with a halo ring, a slightly larger length is recommended in relation to the width, as opposed to a solitaire ring.
