Diamond Engagement Rings: How to choose an Oval Diamond

The oval diamond engagement ring is having a big moment in the spotlight. Beyond its current popularity, this particular diamond shape is a beautiful and timeless alternative to the round brilliant cut. The elongated shape of an oval diamond is flattering on the hand because it accentuates the length of the finger. It also features a combination of modern sparkle and vintage charm. The best of both worlds! But how to pick a quality oval diamond? What to look for when choosing an oval engagement ring?

The Oval Diamond Cut

One of the most important considerations when choosing an oval diamond is its cut. Unlike the round brilliant cut diamond, an oval is not strictly governed by diamond grading parameters set out by the GIA (Gemmological Institute of America). Ovals can vary in length and width. For example, an oval diamond with a 1.6 length to width ratio will be longer and thinner than an oval with a 1.3. This ratio can have a dramatic effect on how the diamond looks. Another important characteristic of the oval shaped diamond is the bow-tie. But what is a diamond bow-tie, and how does it affect the beauty of an oval cut diamond?

What is a bow-tie?

The bow-tie describes a darker section of refraction found across the middle of almost every oval cut diamond. It is named as such because it resembles a gentleman’s bow-tie. The bow-tie is considered to be an inherent characteristic of the oval cut diamond, and for this reason it is not generally taken into consideration when the diamond is graded. A subtle bow-tie can contrast and even enhance the areas a fire and scintillation in an oval diamond. But if the bow-tie is too dark it can be an undesirable characteristic. The only way to asses a bow-tie is to examine the diamond in person.
