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.

At Brilliant Earth we’ve set a new standard in diamond sourcing: Beyond Conflict Free™. We only accept diamonds from specific mine operations and countries that follow internationally recognized labor, trade, and environmental standards. While the Kimberley Process has made advancements in reducing conflict diamonds, it remains flawed and still leaves diamonds tainted by human rights abuses and environmental degradation in the supply chain.
Our metals are created from existing gold jewelry and excess production metal, sourced from refiners that have been audited by the Responsible Mining Initiative and London Bullion Market Association.
Brilliant Earth gives back to help build a brighter future in mining communities and in the communities we operate. We also donate to programs that are dedicated to improving human rights and environmental practices in our industry, including Feeding America, the Rainforest Alliance, and the NAACP Legal Defense and Educational Fund.

Gorgeous ❤️

I absolutely love my ring! I got a white gold Luxe Cometa with a 1.02-carat lab-created marquise cut diamond. I am also very happy that this ring is more low set and flush with your finger, as opposed to being a higher set ring, as I tend to bang my hand on almost everything. I know the pictures aren't the greatest, but holy moly this ring is absolutely perfect and looks stunning in real life! ...Read More
