Softer than a square, yet every bit as brilliant as a round-cut stone, there's a reason why this popular engagement ring shape is so appealing.

There's a reason why cushion-cut engagement rings are so popular. Classic and versatile, a cushion-cut diamond looks just as good as a solitaire as it does set in a halo or three-stone setting. Defined by their rounded corners and 58 brilliant-style facets that resemble a pillow shape, no two cushion-cut diamonds are exactly the same. While some rocks are a bit rounder, others tend to look more like a square.

A growing number of celebrities have been seen sporting cushion-cut engagement rings lately, albeit sizable ones! Kim Kardashian is rocking a stylish 15-carat cushion-cut ring on an ultra-thin micro-pavé band, while Sofia Vergara calls her 8-carat cushion-cut sparkler "perfection."

Cushion-cuts, once known as "old mine cuts," have been favored by brides-to-be ever since the 19th century. Only in recent years has this style soared back into the hearts of newly-engaged women. Aside from looking gorgeous in a variety of settings and metals, the cut's unique shape and rounded corners increase the facet size. In other words, get those sunglasses ready, because these stones are extra brilliant (read: blingy). Since it is an older style, cushion-cuts are pitch-perfect for a vintage-inspired setting (which, have also become really popular lately, especially with Hollywood's hottest celebs), but easily look right at home in a more contemporary halo. The rounded edges undoubtedly make this style a softer one, so while this stone looks great in platinum or white gold, it can just as easily shine in a romantic rose gold setting.

Here, 41 of the prettiest cushion-cut engagement rings we could find.
