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.

Purchased a wonderful engagement ring that will be treasured

I ordered a square cut artificial blue diamond set in a simple white gold ring as an engagement gift. It came within 3 weeks and I was kept update by customer services throughout that time. It looks absolutely lovely and my fiance is extremely happy with it. I was struggling to find a good looking artificial blue diamond and Brilliant Earth had several beautiful ones to choose from. The website was easy to use, I was running through different combinations of diamonds and settings on several websites and found this one the best for choice and seeing what the finished product would look like. ...Read More

Brilliant Earth--Brilliant experience!

Finding the right engagement ring is a seemingly daunting task. You are basically looking for not just a ring, but a band that will compliment a stone that is meant to compliment the person that you're wanting spend the rest of your life with. The ring has to check so many boxes...finding something so unique like that is definitely pretty time consuming and tedious. Especially if you have a certain cut/style/aesthetic in mind. AND THEN, throw in trying to be ethically conscious of the source of your metal and stone. I know this sounds like a sales pitch, but it's not: Brilliant Earth made a super hard task not only easy, but memorable as well. The ring I got was customized to the style that I was going for, and the wealth of information they had on their diamonds made me feel good about my purchase. Will definitely recommend Brilliant Earth to all my friends. ...Read More
