Cushion cut engagement rings

It's true: cushion cut square engagement rings and the elongated cushion cut gets their evocative name from a softly squared pillow. It must be the most romantic pillow on earth! Here at Plum, we're in love with cushion cut lab grown diamonds and only offer a curated selection of designs for you to easily customize. 

Cushion halos are especially sweet for their mix of soft angles and elegant sparkle. The modern cushion cut halo engagement ring is an updated, modified version of the antique cushion cut engagement rings of history books. In fact, the cushion-cut diamond ring has often been associated with royalty. Its feminine, soft lines give a whole lot of sparkle while also being an elegant option for the modern-day queen.

This isn't your grandma's ring, though. A Plum Diamonds cushion cut engagement ring is a timeless, one-of-a-king modern symbol of forever.
