San Francisco Reviews

Was happy to find that they have the exact styles I was looking for in a ring. Liked being able to choose the ring and size of the diamond I wanted. Love all the details that go along with each diamond as well. Also the included gift is a nice touch.

Heard about how great Brilliant Earth is through a friend of mine, and they where right. Ethically sourced diamonds, amazing quality and phenomenal customer service. Was looking for an engagement ring and found just the right one. Love it!!

We had our appointment with Rachel, who was thoughtful, knowledgeable, and personable. Since they arent commission based we never felt pressured and the experience helped us narrow down the type of ring. Rachel asked very specific questions based on my girlfriends likes and dislikes and wrote detailed notes for us to take home.
