Best Carat Size for Radiant Diamond Rings

Three different Radiant cut diamond settings

An engagement ring is arguably the most important piece of jewelry a woman will wear in her lifetime, one that could easily become a precious family heirloom in one or two generations. Of course, you want it to be perfect. So you head to your nearest jewelry store (or Google an online retailer) and look for the greatest diamond engagement ring you can find to buy.

You look at round diamonds, heart-shaped diamonds, and pear-shaped diamonds, but none of them seem to capture the style of your intended. Then you happen upon a rectangular diamond that sparkles with a unique, fiery quality. When you look at it, it is not hard to see how this diamond cut got its name--radiant. That, you think, is the diamond for the woman you love. Excellent choice! The multifaceted, glittering stone is bold, eye-catching, and beautiful, making it a popular pick for engagement rings.

But once you’ve settled on the radiant shape, another challenging question awaits. What size diamond is best? There are many factors to consider when you pick the carat for an engagement ring. While you do your shopping, consider the following:

Radiant Size for Her Hands

We doubt you’ve have spent much time staring intently at your girlfriend’s hands during your relationship, even if you hold it often. But now is the time to start. You want her engagement ring to flatter her fingers, not distort her natural beauty by being too large or too small for her hand. Radiant cuts best suit ladies with wide, strong fingers. In fact, an elongated diamond that spans the length of her finger can make her hand look more slender and elegant. As you’re looking at different carat sizes, consider the size of her hands. Try and choose a carat size that shows as little skin as possible on either side.

The Radiant Setting Design

The setting you choose for your radiant cut diamond plays a big role in the carat size you’ll want. After all, the setting completes the look, and you’ll find that with some settings, less is more. For example, a solitaire setting or a band with baguettes would warrant an average to larger-sized stone. The thin setting will give that radiant diamond room to shine (and, if you’re looking at the smaller sizes, a thinner band can make the diamond look larger).

Don't Forget the Radiant Halo

Say you opt for a setting that features a halo; this might be a time when a smaller diamond is suitable--a cost-effective option for those folks on a budget. The pavé diamonds circling that radiant rock will add plenty of additional sparkle, but a big diamond in the center could be bordering on overkill.

One thing is for sure: whatever size your decide on, the radiant cut diamond will make for a striking ring that you’ll be proud to propose with and that she’ll be proud to put on her finger!
