The perfect upgrade

After getting engaged and married at 23, it was time to upgrade my wedding ring. I really liked the emerald cut and I am so happy we chose to go with this style! It's simple with just the right amount of extra bling. Are the only downside is that it is a little hard to find a wedding band that matches perfectly. But that is really just a minor thing. ...Read More

A stunner

I'm really happy with the service provided by Brilliant Earth. Their representatives took the time to review engagement ring options with us, and explained the different advantages/disadvantages to ring styles & cuts. I'm also really impressed with how green the company is and the way they address climate change & issues with the diamond industry with their eco-friendly and humanitarian practices. My fiance is extremely satisfied with the ring I purchased, and we plan to buy our wedding bands here as well. Thanks BE. ...Read More

Excellent Experience

I can't say enough great things about our experience with Brilliant Earth. My fiancé and I went in together to look at settings and get an idea of what she liked. We worked with Julie at the Georgetown location and she was phenomenal! We ended up with the Tapered Baguette setting. After the initial appointment, I worked with Julie for weeks to select the perfect diamond. I had many questions throughout the process and Julie was very prompt and answered them all. The buying process was very smooth and easy. There was a shipping delay but that was to be expected because of all the shipping delays around the country. We are so thrilled with the engagement ring and the customer service at Brilliant Earth. If you are in the Georgetown area, I highly recommend Julie. We look forward to going through the wedding band process with Brilliant Earth in a few weeks. ...Read More
