Best Brilliance went above and beyond our expectations. They sent us a beautiful ring and when we wanted to make adjustments they were easy to get ahold of and made sure our revision request was perfect. We couldn’t be happier with our experience and the great customer service the team provided.

Hi Ryan,
It’s great to hear that we hit the mark for you. We know that sometimes a "revision" can feel like a headache, so we make it a point to stay easy to reach and ensure the final tweaks are spot on. I’m glad the team could make that process smooth.
Wishing you both a lifetime of good health and a marriage full of love.

Great company the pictures does no justice for how magnificent the ring actually looks in person. My fiancée loves it and get compliments on her ring every time

Hi Roscoe,
Congratulations on your engagement!
We often say that even the best photography can't fully capture the fire and brilliance of a hand-crafted piece. I am thrilled to hear that the ring exceeded your expectations in person and that your fiancée is enjoying the compliments.
Wishing you both a lifetime of good health and a marriage full of love.

Top Tier follow up!
**EDIT**
WOW WOW WOW. I can’t believe the level of urgency that the team took to make things right. Not only did they take care of the problems that I had, but they ended up going above and beyond to make sure the experience I had from the beginning was replicated! I appreciate the team over at Best Brilliance!
**EDIT**
The team over is working diligently to solve these issues. I spoke with Adam, and he was and he truly cared about the experience i’ve had so far.
**ORIGINAL**
I had a great experience initially with Best Brilliance — the communication with my rep before receiving the ring was honestly 10/10. Everything felt smooth, responsive, and professional during the buying process.
However, things completely changed after I received the ring.
When I reached out regarding issues, I got no response at all. Just one day after receiving the ring, I was notified that the warranty was void, which was extremely frustrating, especially since there was a complimentary warranty promotion advertised with the purchase.
On top of that, after only a couple weeks of consistent wear, the ring turned cloudy, and I went with one of the highest quality options. I chose one of the higher-tier qualities expecting better durability.
Overall, the lack of post-purchase support and the quality issues were very disappointing. Based on this experience, I can’t see myself purchasing from Best Brilliance again.

I asked for a custom band after I ordered and my personal contact which was assigned to me and proactively reached out handled it for a very small cost. I couldn't be happier. Also...She said YES!

We are thrilled to hear the big news. Congratulations to you both!
Providing a personal contact is how we ensure every custom detail is handled with precision. I am glad we could accommodate the custom band for you at a fair cost and that the final result met your expectations.
Wishing you both a lifetime of good health and a marriage full of love.

Great customer service & Beautiful ring
I initially had an issue with receiving a ring that did not match the expected specifications, but their team, especially Paul & Mary, worked with me directly to resolve everything in a fair and professional manner. They were responsive, followed through on their commitments, and made sure I was taken care of, which I really appreciate.
Most importantly, the final ring turned out absolutely beautiful. The craftsmanship and overall quality exceeded expectations, and my fiancée loves it.
Because of how they handled the situation and the end result, I’m happy to leave a five star review. It is clear they stand behind their products and are willing to make things right for their customers.

We take full responsibility for the initial oversight, and we appreciate you giving us the opportunity to correct it. At a boutique house like ours, we stand behind every stone and setting we produce.
I am glad Paul and Mary could provide the professional, direct resolution you deserved. Hearing that your fiancée loves the final ring and that the craftsmanship exceeded expectations is the best possible outcome for our team.
Wishing you both a lifetime of good health and a marriage full of love.
