Cushion

A cushion diamond was the favored diamond shape until the early 20th century, but its classic look has resurfaced in recent years, becoming one of the most popular diamond shapes available. True to its name, its rounded corners resemble a pillow.

The Hope Diamond—one of the world’s most famous—is a 45.54ct cushion cut.

Cushion cut standards vary more than other shapes, so don’t be afraid to let personal tastes guide your choice. It’s a versatile cut, so simple changes in facet structure or ring setting allow you to style the diamond to feel more modern or antique.

After the round cut, the cushion cut offers the most fire and brilliance, making it a great alternative for those who like the classic sparkle of a round diamond.
