Cushion cut engagement rings

It's true: cushion cut square engagement rings get 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. Made with lab grown diamonds that are ethically sourced and deliver the absolute biggest bang for your buck: you get all the quality and carat weight that you want for a fraction of the price of a mined diamond. You never need to worry about ethical quandaries when choosing a Plum Diamonds lab diamond engagement ring, as there isn't a mined diamond in sight.

We've crafted thousands of lab grown rings and have learned through the years how great design and manufacturing integrity can live in harmony. That's why we only offer intuitive customization options that make sense and create timeless cushion cut diamond designs.

Whether it’s a cushion cut solitaire or a rose gold cushion cut engagement ring, you're making a promise to last a lifetime and so are we, providing free lifetime servicing to keep your cushion cut lab grown diamond engagement ring in tip-top shape.
