Diamond Ratios and Why They Matter

Diamond ratio refers to the proportion of a diamond’s length to width. Specifically, it’s the ratio of the length to the width as measured at the diamond’s widest point. For example, if a diamond is 6mm long and 4mm wide, its ratio would be 1.5.

Why is this important? Well, a diamond’s ratio can affect its appearance. Diamonds with a higher ratio, meaning they’re longer and thinner, tend to have a more elongated appearance. This can be desirable for some people, but not for others. Diamonds with a lower ratio, on the other hand, appear more round.

So what should you look for in a diamond ratio? Ultimately, it comes down to personal preference. If you like the look of a longer, more elongated diamond, look for a higher ratio. If you prefer a more traditional, rounder diamond, look for a lower ratio.

That being said, there are some general guidelines you can follow. Most experts recommend looking for a diamond ratio between 1.5 and 1.75 for a classic round diamond. If you’re looking for a more elongated shape, a ratio between 1.75 and 2.25 can be ideal for shapes like ovals, marquises, and pear-shaped diamonds.

When shopping for a diamond, don’t be afraid to ask the jeweler about the diamond’s ratio. They should be able to provide you with this information, along with other important details like the diamond’s cut, color, and clarity.

In summary, the diamond ratio refers to the proportion of a diamond’s length to width, and can affect its overall appearance. While personal preference plays a role, it’s generally recommended to look for a ratio between 1.5 and 1.75 for round diamonds, and between 1.75 and 2.25 for more elongated shapes. By understanding the diamond ratio and what to look for, you’ll be better equipped to choose the perfect diamond for you.
