Made Just for You

At our San Francisco design studio, our team designs every ring to delight you, from the first time you see it and every day after. We carefully consider the entire piece—obsessing over comfort, quality, and durability so you can cherish it for a lifetime.

Today 98% of our gold and 97% of our silver is recycled because we care about miners, their communities, and the environment. By 2025, 100% will be recycled or Fairmined. We say no to ‘dirty gold’ because we know how destructive new gold mining can be.
Our packaging uses recycled materials made with less energy, less water, and fewer emissions. We make our iconic ring boxes with wood certified by the Forest Stewardship Council and design them to last lifetimes. Since 2021, we’ve used 100% recycled paper, saving hundreds of tons of CO2, and we’re shrinking our packaging even more to further reduce waste.
We’re leading the jewelry industry towards clean energy. We use clean energy in our showrooms and offices, have displaced all other corporate emissions since 2018, and support wind and solar energy projects through collaborations that help address climate change.

Beautiful and unique

This is the wedding band my husband chose in rose gold. We love the uniqueness of it. He thought every other ring looked so boring and they all looked the same that is until he found this one. He's the Celtic look of it and it also matches the Celtic trinity engagement ring he got me also from brilliant earth. We love how they look. He also says that it is a very comfortable band. He is very pleased with it. ...Read More
