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.

Our wedding band

Bought two for our wedding bands and we are very satisfied. 2.5mm for my wife's and 4mm for myself (yes, you can order with a different width. You should pay more for extra metal if you make this thicker). We also tried the similar design bands from Tiff*** (we were looking for a flat band, and Tiff*** also has one), but we liked BE's more. ...Read More
