After 2 years, I'm still in love 💍✨

When I first received this ring, I was super happy, yet sad at the same time. Because... it was cutting me up along with whoever was around me (ouch)! I was pretty bummed out. I did NOT want to take it off because the ring was so gorgeous and of course being newly engaged. So we contacted Brilliant Earth and with their supportive customer service, we were able to get the sharp edges fixed. Overall, this ring is stunning, gives vintage vibes, which I love, and its unique compared to your traditional engagement styles. The Dahlia paired nicely with the Tiara wedding band (also from Brilliant Earth). ...Read More

Absolutely gorgeous

I get nonstop compliments about my ring. I told my fiancée exactly what I wanted though 😂 I went with marquise instead of a classic round and I think it just adds to how gorgeous it is. It's perfect beyond words. ...Read More

Perfectly Unique

My fiancé and I absolutely love the way my ring turned out. I gave him some ideas and wanted something unique and the Dahlia absolutely delivers. It definitely gives off hints of modern while still being different than most engagement rings. The pear directional diamonds are gorgeous, but definitely are a little sharp. That goes away after a day when you get used to having the ring on your hand. The center stone is 1.25 carats and I think anything bigger may look too big. It comes up off the finger about a half an inch, so it doesn't get caught on things, but also doesn't sit too close to the finger. The band is also a great width and gives room for a wedding ring. We are just so pleased with the ring and our overall experience. I would highly recommend using Brilliant Earth for your engagement ring! ...Read More
