Perfect Oval Diamond Dimensions: How to Calculate Them

Oval diamonds have been around for quite some time, but they’ve really taken off in popularity recently. The thing about oval diamonds is that they have this classic vibe with a twist. They’re not your traditional round diamonds, but they’re pretty close too. For example, Hailey Bieber’s engagement ring is an oval-cut diamond in 18k gold.

One of the big reasons people fall for oval diamonds is because they have a way of looking bigger than they actually are. It’s all about the shape. The elongated oval can make the diamond appear larger on the finger, which, let’s be honest, is a pretty sweet perk. Plus, they’re known for their sparkle. A well-cut oval diamond can catch the light in a way that’s just mesmerizing. So, the dimensions matter a lot in the oval-cut diamonds.

Oval Diamond Length to Width Ratio

Length to Width Ratio

First things first, the “oval diamond length to width ratio” is a big deal. This ratio tells you how long and wide the diamond is, which directly affects how it looks. Some people love a longer oval because it can make the finger look a bit more slender. Others might prefer something closer to round, feeling it’s a better fit for their taste. The ratio helps you figure out the diamond’s shape before you see it on your finger. A common favorite is the 1.5 ratio oval diamond. This means if the length is 1.5 times the width, you’ve got a nicely balanced diamond—not too long, not too squished.

How to calculate the oval diamond ratio:
  1. Measure the Length: First up, you need to find out how long your diamond is. Measure from one end to the other, straight down the middle. This is your length.
  2. Measure the Width: Next, you’re going to measure the width. This time, you’re measuring across the diamond at its widest point. This gives you the width.
  3. Do Some Simple Math: Now, take the length and divide it by the width. So, if your diamond is 8mm long and 5mm wide, you’d do 8 divided by 5. The number you get is your ratio. Using our example, 8 divided by 5 gives you 1.6. So, the ratio of your oval diamond is 1.6.

When you’re out there looking for an oval diamond, think about what kind of look you’re going for. If you’re not sure, ask to see a few different ratios. Try a 1.3, a 1.4, and a 1.5, and see which one jumps out at you. Remember, there’s no “best” ratio—it’s all about what you like and what looks good to you.

The Best Table and Depth for Your Oval Diamond

What’s the best size for the table? Generally, a table that’s about 53% to 63% of the diamond’s width is considered a good spot. If the table is in this range, you’re likely to get a diamond that interacts with light in a beautiful way, giving you that sparkle we all love.

Depth is all about how tall your diamond is from the bottom to the top. For oval diamonds, a depth percentage between 58% and 62% is often seen as the sweet spot. This range is just right for allowing light to travel through the diamond, get reflected, and come back out, making your diamond shine bright. A diamond with the right table and depth percentages has a better chance of hitting that perfect balance between being too dull and too flashy. It’s about getting a diamond that sparkles just right, not too little and not too much.

It turns out, a lot of people chose oval diamonds with a ratio of about 1.5:1.7 This means the length of the diamond is 1.7 times its width. This ratio hits a sweet spot, making the diamond look elegantly elongated without being too skinny. But it is more common to find ovals with ratios between 1.3:1 and 1.4:1. These diamonds are a bit rounder, but they still have that graceful oval shape that sets them apart from the classic round diamonds. It’s all about what catches your eye and fits your style.

What are the Perfect Oval Diamond Dimensions

There’s this thing called the bow-tie effect that comes up a lot when talking about oval diamonds. It’s a black bow tie in the middle of the diamond. That’s what we’re talking about. It’s not something every oval diamond has, but it’s pretty common. The bow-tie effect happens because of how the diamond is cut. Take your time to look at the diamond from different angles. 

Finding the perfect oval diamond can be a simple mission filled with technical lingo. It’s about what you love looking at. Whether it’s the more popular elongated shape or the classic roundness, what matters is that it’s perfect to you.

Notice how it catches the light and whether it has a bow-tie effect. Does that add to its charm for you, or would you rather not have it? Remember, the perfect oval diamond is the one that makes you smile every time you see it sparkle.
