Oval Diamond Engagement Rings

Oval Diamond Engagement Rings – Read This Before Buying

Oval diamonds are my favorite type of diamond. They are elegant, unique, and very brilliant. I know a lot about them, and I proposed with one myself (the oval diamond and dainty engagement ring at the top of this page is the ring I purchased for my fiancé)! If you are looking for oval diamond engagement rings, here are some of the benefits of choosing one, as well as very important tips on choosing one.

Oval Diamonds Appear Larger Than You’d Expect

When most of us think of diamond size, we envision the top surface of a round diamond. If you replaced that round diamond with an oval diamond that’s the same carat weight, the top surface would usually appear to be larger. This is because an oval diamond often has a greater surface area than a round diamond of the same weight. For example, an average 1 carat oval diamond has a 10% larger surface area than an average 1 carat round diamond. This means that you can get a diamond that looks larger, for a lower price.

Oval Diamond Engagement Rings Make The Fingers Look More Slender

Because an oval diamond is elongated, oval diamond engagement rings may give the illusion of slightly longer and more slender fingers. Whether this is a good thing or bad thing is a personal choice.

The Length to Width Ratio is Important

All oval diamonds in our diamond search engine will have a length to width ratio listed. This ratio will help you gauge how narrow or wide the diamond is. A greater length to width ratio means the diamond will be longer and skinnier, while a lower length to width ratio means the diamond is more circular (a round diamond has a length to width ratio of 1). Most people prefer oval diamonds with a length to width ratio from 1.3 to 1.7, however this is completely up to you. I personally prefer oval diamonds with a length to width ratio in the 1.4 to 1.6 range.

You Should Not Pay More for an Oval Diamond

While oval diamonds are more rare than round and princess-cut diamonds, they are also in less demand. You should not have to increase your budget when looking for oval diamond engagement rings.

Oval Diamond Engagement Rings are Very Sparkly

An oval diamond is cut the same way as a round diamond, and so even though a round diamond has the most brilliance of all diamond shapes, an oval diamond is very close. Oval diamond engagement rings are perfect for someone who likes the brilliance of a round diamond, but wants something more unique.

Warning: Oval diamonds are not graded by the GIA for cut. In order to end up with a beautiful oval diamond engagement ring, make sure your jeweler understands the optimum oval diamond cut specifications. The below table should help you narrow down your choices, but never buy an oval diamond based on the certificate only. You really need to find someone that will perform a visual inspection before you purchase the stone.

Optimum Table & Depth for Oval Diamonds

Ideal/ExcellentVery Good
Table (%)53 – 6352-53 or 63-64.8
Depth (%)57.5 – 6256-57.4 or 62-65

You Can Get an Oval Moissanite or Oval Sapphire Engagement Ring

The oval shape is available in moissanite and gemstones, including sapphire. In fact, Kate Middleton’s engagement ring (that was originally Princess Diana’s) is a beautiful oval sapphire. Oval moissanite and oval sapphire are much more affordable than oval diamonds, and my post on affordable engagement rings cover these options in more detail. Contact us if you want to discuss these options.

Your Oval Diamond May Have a Bow-Tie Effect

Most oval diamonds have something called a bow-tie effect. This effect occurs when light doesn’t bounce back in the middle of the diamond because of the way the diamond is cut. While most diamond cutters agree that this is part of the beauty of the oval diamond, you do not want the bow-tie effect to be too severe. Because bow-tie effect isn’t taken into consideration when grading a diamond, it is not noted on a diamond certificate. The only way to gauge how severe a diamond’s bow-tie is is through visual inspection. Below is a picture from the visual inspection I performed before purchasing my fiance’s diamond. Her diamond has a small bow-tie in the middle, and I like this picture because the contrasting black background makes the bow-tie easy to see. This is the same diamond that’s pictured at the top of the blog post, where you can see that the bow-tie effect is fairly small and beautiful.

Always have your jeweler perform a visual inspection of your oval diamond to make sure it does not have a severe bow-tie.
