There are plenty of lab-made diamond engagement rings, like those from Brilliant Earth, to choose from. Don’t know where to start?

Brilliant Earth’s Secret Garden Engagement Ring is a whimsical ring for a non-traditional bride.

This ring is specifically designed to showcase a center lab diamond, but the shape and carat are customizable, and there are four metal options. We personally love the 14k Rose Gold, which heightens the look and feel of the diamonds.
