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.

Having an open band isn't something I even knew I wanted until I tried it on in a brilliant earth store. This ring is stunning and I love the way it almost "points" to by engagement ring. I paired it with the Freesia (with an 8x6mm oval moissanite) and love the look. Photos are on my size 5.5 finger. ...Read More
