Grown Brilliance Reviews 

I purchased the graduated engagement ring and while back and now decided to purchase the matching band. The band is much smaller size and doesn't match well at all. And for the price of the band alone I expected something much better.

My wife is very happy with the ring it’s beautiful. This is my second purchase from GB and I will continue to buy from here in the future.

Without having seen a diamond to make a selection I decided to buy online based on Grown Brilliance reviews and their easy to follow selection and configuration process on their website. I am completely satisfied!
I received the exact excellent cut, color, clarity as promised and the Princess Cut diamond has amazing brilliance and fire. It is as clear as glass. My wife is incredibly happy with her surprise gift. And you will be amazed at the price of a lab grown diamond vs a mined diamond.

Well.... you helped me to make a very special woman happy. She's definitely enjoying the engagement ring and will soon be enjoying the wedding band to match.

I created a custom pair of ear cuffs with Emy. She was wonderfully patient when choosing the size of the diamonds so the thickness of the cuff was exactly what I wanted. She explained the process of creating a custom design and it was everything she said it would be - a full size spec sheet with all the dimensions, actual size, etc. Like an architectural drawing. Look into their custom process. It is so worth it! They arrived earlier than I expected and I love them! I wear them as singles or stacked as a double.

Im very happy with my ring. Its very comfortable. I didnt want a ring that overstated. This one is the perfect size. 1ct, size 6

I love the product. The only suggestion I would make is to allow buyers know the tennis bracelets are custom made. I ordered this for my fiancé for Christmas and it made it 35 days later. But great producr

I ordered a necklace on Jan 14th. Expected time to ship was Jan 27th. It is now February 5th an it has not shipped. Oh, I understand that was an expected ship date. But, why not be honest with your estimated ship date? I don't know anyone who would be happy that you are 9 days off on your estimate. Im guessing i still have more days of waiting. If you arent prepared for an order bc you have to make this that or the other. Then that should be factored into the estimated shipping date.
On time delivery is important to people so try be honest. Im sorry but i can't recommend this company.

I was apprehensive buying online but in this case it was easy and fast and even great follow up from GB

The rings that I purchased from grown brilliance were absolutely amazing. The sales girl at the Boca Raton location was amazing as well.

In 2023, I purchased an IGI Certified Lab Grown Diamond engagement ring from Grown Brilliance, featuring a Marquise Shaped, Excellent Cut, E-VVS2 stone. Although I initially had reservations about the main diamond's lack of brilliance, I didn't voice them as my partner was happy.

Unfortunately, the diamond soon began to appear cloudy, losing its clarity, while the smaller accent diamonds retained their sparkle. When I contacted the vendor, they recommended professional cleaning. The cleaning restored the brilliance, but only for one or two days before the cloudiness returned. A subsequent cleaning prompted the jeweller to express concern, noting this recurring issue was highly unusual. Because of its dull appearance, my wife became self-conscious and stopped wearing the ring, feeling it looked fake.

For our anniversary on December 1st, I asked her to wear the ring. Upon observing the cloudiness, we consulted a second jeweller. They cleaned the ring, but again, the sparkle faded within days. A follow-up visit led the jeweller to examine the certificate and confirm its authenticity. However, they concluded there seemed to be an inherent flaw, describing it as a "low quality diamond, even by lab grown standards," suggesting a poor carbon composition.

I contacted Grown Brilliance again. They dismissed the issue, blaming external factors like oils and lotions. They argued the issue is not covered under warranty, claiming that since the diamond sparkles after cleaning, there is no inherent defect. This contradicts the fact that the wedding band and the accent diamonds remain brilliant. This situation has caused a significant financial loss and, more importantly, disappointment to my loving partner.

***Their response is consistent. Nothing is ever wrong with their product, even though there are 2 independant jewellers that disagree. We actually cleaned it and left it without wearing it. A week later it is cloudy. We have other diamonds in the same storage area. Perfectly brilliant. ***BUYER BEWARE**

The diamond we ordered and had made into a ring is very nice but is not what we ordered. We ordered a 3 carat Asscher cut diamond. What we received was a 3 carat square emerald cut diamond according to the IGI report. It's easy to research that these are similar but different cuts. We like the ring but it is not what my wife wanted. She likes the look of the genuine Asscher cut which looks very old fashioned. I called customer service last night when I finally realized the difference and to be honest I got pretty upset with the person who was trying to convince me that they were 2 names for the same cut. A simple 2 second Google search shows they are not. I demanded a call back from a person on Monday, and from someone in America as the person I was speaking to was clearly in India. No problem with outsourcing calls to India since it is a jewelry center but I don't see how someone half a world away can solve this situation. I hope for a good resolution to this then I can change this review to a higher level. We previously bought a 5 stone wedding emerald cut wedding band which we've had no problem with. Again the ring is quite beautiful but not what we ordered. My daughter had previously bought a 3 carat wedding ring from you which is beautiful and had no problems. Anyone who buys a "natural" diamond nowadays thinking it's an "investment " is a fool by the way.

Product (wedding ring) was beautiful. Then within a year a sideshow had fallen out & we had to send it back under their lifetime warranty. We requested them to look at & fix the outings as well since one was snagging on clothes, etc & we did not want to lose the big diamond. They fixed the ring. Then within a year a prong broke (which we asked them to look at on prior return). This time they stated that this was normal wear & year and not covered under their lifetime warranty (nor can you purchase their insurance since not within 30 days of purchase & don't know if this would cover the required repairs). How are we supposed to know at time of purchase that the ring was of inferior quality parts? My wife has rings from well over 50+ years old with no problems (her mom's wedding ring plus trying from prior marriage). I would not buy from this company due to major product quality concerns. Why buy a beautiful ring that you cannot wear?!

UPDATE FEB 13, 2026: I RECEIVED MY MISSING ITEM QUICKLY AFTER FILING A COMPLAINT. LOVE THE RINGS. COMPANY NEEDS TO IMPROVE ITS COMMUNICATION. I ordered and paid for 2 rings on Dec 25th. Only one arrived on Jan 13th. I reported the issue immediately to customer service. I've now called six times for an update and am receiving conflicting stories for GB's customer service. Deeply concerned that I've paid for an expensive item that I'll never receive.

Product is spectacular and ordering process for this custom item was seamless.

I tried on many styles of wedding bands before walking into GB, so I had a good idea of what I was looking for. The sales associate was still incredibly helpful in talking through my vision and finding what I was describing. Everywhere I looked I only saw either 5 or 7 stone bands… but i found the most incredible 8 stone band here so a diamond isn’t hiding under my main stone on my engagement ring!

Staff was very knowledgeable on their products and understood what I wanted perfectly. Very efficient delivery timing and smooth transaction.

Gorgeous ring. Easy ordering process and arrived beautifully packaged.

The woman that helped us was extremely patient and kind of how she shared in our experience. It's wonderful to still have some places where customer satisfaction is prioritized over volume of sales. Alexandria really treated us well.
