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.

Gorgeous ring

I bought this ring as an engagement ring. I had a 5.5mm Sri Lankan sapphire set as the centre stone with yellow gold. It looks amazing, and most importantly she said yes. :D ...Read More

First Class Product

I purchased this as an engagement ring and it did not disappoint! I was absolutely stunned with it when it arrived and she still hasn't gotten over how beautiful it is even after 3 months! It is extremely well made and the quality is top notch. The polish was flawless, the diamonds set perfectly, and the fit couldn't be better. When it comes to making things look nice, I am extremely picky when it comes to detail and after looking over this ring for the past few months I still can not find anything I would change about it. The durability has been great as well. She is an aircraft mechanic and pilot by trade and even though she doesn't wear it while turning wrenches, it has held up very well in everything else. We recently had it cleaned and there are no visible scratches or damage of any kind. I will not hesitate for one second to purchase from Brilliant Earth again! ...Read More

Beautiful Setting, Excellent Service

I love the semi-bezel setting of this ring. I'm hoping it won't catch on to anything and the main diamond will not easily become loose. I plan to wear this everyday so it was important to have something simple & durable. I stayed away from pavé settings for this reason. Only time will tell if this lasts, but I have been wearing it for over a month and only the side stones have briefly caught some fuzz from my sweater. I didn't get a large diamond (.58 from their Glacier collection), but I didn't have to because the setting makes this diamond sparkle and pop. I can't stop looking at it as I type. I was concerned with the "wave" but it perfectly complements my contour wedding band. It doesn't sit flush all the way but it's pretty close for something that's not custom made and bought from another place. Attaching some pictures for reference. The band itself has some small scratches already but I think this is expected with 18K gold -- and it's on the backside so not easily visible unless you are looking at it. The prices was slightly higher than others but the beautiful product, great customer service and the renewable metal and conflict-free diamond makes this purchase well worth it! ...Read More
