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.

Exactly what I ordered

Nice but poorly constructed

Took the ring in for resizing and the jeweler pointed out that the side diamonds were very loose and would eventually fall out. Only 2 prongs. I had to pay an additional $100 to have her add prongs to hold them in place permanently. Not that thrilled. ...Read More
