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.

Our commitment to transparency began with the Beyond Conflict Free™ standard we pioneered. We select diamonds for their ethical and environmentally responsible origins, besting the industry standard of merely “conflict free” — which is narrowly defined as diamonds that finance wars against legitimate governments. Our diamonds provide miners with fair wages and safe working conditions, empower their communities, and never fund wars.
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.
From mines to Main Street, we care about building better communities by compassionately giving back. In 2021, we started the Brilliant Earth Foundation to focus and amplify our impact. Since then, we’ve donated $2 million towards leaving communities better than we found them – from the areas where precious materials are mined to the communities where our team and customers live.

So beautiful!

I love this ring! The setting is beautiful - I recommend going to one of the Brilliant Earth stores and trying the rings on in person. I didn't even have my eye on this setting when shopping online, but loved it the most in store! I have it set with a 1 ct pear lab diamond - absolutely stunning :) ...Read More

Looks amazing!

A ring almost as beautiful as the woman I gave it to. Can't recommend Brilliant Earth nearly enough to my friends! I bought the ring a bit too big and customer service notified me of the free responding. The resizing was handled exceptionally well, and the ring was back to us in no time. Thank you guys! ...Read More

Amazing ring and the sparkle is amazing. The thicker band is more flattering for people with larger fingers. ...Read More
