When Zendaya walked the 2025 Golden Globes red carpet, all eyes were on one thing: A big, beautiful diamond ring that sat on the fourth finger of her left hand. Fans were quick to speculate that it was an engagement ring,

Thanks to Zendaya, the untraditional diamond setting—almost impossible to find until about five years ago—is having its time to shine.

"When you think of a traditional solitaire engagement ring, elongated diamond shapes such as emerald or oval cuts will be set 'north-south' or vertically," explains the jeweller Rachel Boston. "An east-west engagement ring features a stone that has been set horizontally, with its most elongated side set parallel to the ring band."
