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 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.
We present each Brilliant Earth design in a jewelry box crafted of wood from Forest Stewardship Council (FSC) certified forests—trees that are managed and harvested in a manner that protects and maintains natural communities and respects the rights of workers and indigenous people.
As part of our commitment to protecting the planet, Brilliant Earth is Carbonfree®. We calculated our carbon footprint by assessing the direct emissions of our energy use, including packaging, shipping, and employee travel and commuting. Then we partnered with Carbonfund.org to offset our carbon emissions by contributing to Tropical Rainforest Conservation in Brazil. We will continue identifying ways to reduce our footprint and offsetting emissions that we cannot eliminate.
