Lisa Coriaty was simply AMAZING!
Lisa Coriaty was simply AMAZING!! She always took the extra time to give me such detailed explanations whenever I had questions. At times, I was unsure about my selection as far as the specific details in creating my ring which was for my 31st anniversary. Lisa always responded with very detailed information which really gave me peace of mind. She made this entire process so much easier for me with our conversations and her warm and comforting emails.

We ordered the Kaylee Lab Grown Diamond Rose Gold 2 Carat ring. We worked with Paul during the whole process and he was fantastic. He helped us with all of our needs and wanted to make sure we were 100% satisfied. I greatly appreciate all the help he provided. The customer service from this company is absolutely amazing.
Well ...
Well .... To me the best brilliance web site and all seems a bit sketchy. Now that said We have bought two entirely different rings that each of us loves so far. Mine is a recent Mens gold ring and my Wife has a Moissanite ring she has had six months or so that she loves!
Quality seems good. I feel the ring I got was overpriced. I did willing go with it because it seemed the exact style I really wanted, so that's on me. It is cool, I like it, just what I wanted. (Caveat, I would have preferred 14k over 18k for strength, durability etc.)
So far so good!

i fell in love with two different rings. i did order both, one fast 6 day shipping and the other standard. they both came in on time. i was so so nervous because this was an online website, some reviews were questionable but i am so happy with both rings delivered. the only thing i would love to see on the website is more real life photos of them on a person. the ones generated feel AI or computer generated. overall, it was exactly what i was hoping for and i will without a doubt be buying more from this company

Top-tier customer service
Paul reached out to me after some miscommunication with the shipping department(not their fault) he worked fast to make sure that everything was correct in the end.

Engagement Ring
Beautiful piece that helped me turn a special day even more special.

Stunning!
My husband and I bought this engagement ring to replace my mother's diamond that I lost - which was a diamond from the 1950s with zero imperfections - a hard thing to replace for both sentiment and value. BUT - this ring is everything I have ever wanted. It needed a bit of modifications, which were taken care of with ease and care (thank you SO much)! If you are hesitating for any reason - don't wait! You'll be happier than you ever thought you could be!

A Masterpiece
I’ll admit I was nervous about ordering an engagement ring online, but Best Brilliance completely changed my mind. From the first message, their team was patient, clear, and incredibly responsive. Every question I had was answered quickly and with real knowledge, not generic replies.
They helped me choose the right diamond and setting for my budget, sent photos and videos before production, and kept me updated at each stage. The whole process felt personal and transparent, which is rare when buying fine jewelry online.
When the ring arrived, it was even more beautiful than expected. The craftsmanship is outstanding and the presentation felt luxurious but still down-to-earth. Everything came with full certification and perfect packaging.
I had one small follow-up question about resizing, and their support handled it immediately with genuine care. You can tell this company actually stands behind its products and values its customers.
I’m genuinely impressed. Best Brilliance combines great prices, honest communication, and top-quality jewelry in a way that’s hard to find today.
Highly recommended.
