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.
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.

MORE BEAUTIFUL THAN IMAGINED!!

I shared three permutations of this ring with my fiance and left it to him to choose the one he liked best. He chose an unheated teal sapphire center stone that he felt matched my eyes to go with the 3/4 ct tw side diamonds. I have small hands (size 4), and this ring is neither too small or too large. It's my DREAM ring -- elegant, stylish and classic! < 3 ...Read More
