The shape of your diamond matters, but picking it can be hard. Learn more about popular cuts before committing to an engagement ring.
Every diamond engagement ring—peeking out from its tiny box, glinting in the light—is as unique as its wearer. That's because no two stones are alike. But to narrow down your favorites, consider the cut: Those angles and facets go a long way in defining a ring's personality, and reflecting yours.
To help you pick your perfect match, we've broken down the different style categories. We've also provided storage inspiration, by way of ring boxes that complement each diamond shape. A cute velvet box is a sweet place to put your ring (when it's not on your finger!). These were made for us by Weft and Whimsy (heart, lips, Popsicle, berry, triangle, and rectangle shapes), Amonié (round), and Secret Keeper Box (octagon).

Trendsetters—whether in fashion or décor—have embraced the art deco–inspired, graphically pleasing lines of geometric shapes in recent years. And jewelers are no exception. Look for styles like hexagonal rose cuts and starburst designs (a center stone surrounded by baguettes, for instance) to make a serious statement.

And some designers have taken to combining multiple diamonds to create a whole new shape—a star, for instance, or the flower-petal look of a double pear. These are some eye-catching sparklers.

In the Round
The round diamond solitaire is a classic for a reason. It's simple, universally flattering, and, thanks to the brilliant cut, almost always the sparkliest pick. Oval cuts—another versatile shape that is especially stunning when set with smaller stones—are on the rise, though.
