Such a brilliant company! The rings are beautiful and customer service is fantastic. I originally had ordered the wrong size but Amanda and the team got my issue sorted within a few weeks. Hands down... See more

Beautiful creations
Beautiful creations, quick responses to emails, and value. Its all great!
Beautiful, high-quality ring!
Easy to order and change your order (I added engraving and changed my size after my initial order). Purchased an emerald stone set in a men's platinum band. BEAUTIFUL!!! High quality!
The customer service was excellent
The customer service was excellent, they were kind and responded very fast. I must admit that the quality is top notch, my ring came beautifully and with no errors, just like on their website.
Very friendly and responsive…
Very friendly and responsive customer service. They let me know when my custom ring was taking slightly longer to make and kept me updated through the whole process. The ring came in luxurious packaging and the ring looks absolutely stunning!
Nothing at this time.
I LOVE my ring!
I LOVE my ring, it far exceeded my expectations! The ruby and diamond stones ended up larger than I ordered, and the diamond is a very good diamond. It came with an IGI grading report and was laser inscribed, which very much surprised me. I would highly recommend Diamondere, and will definitely be looking at buying more from them!

Lifelong customer can 100% recommend
I have only had one experience with this company, and it went so well that I have returned and will continue to do so for years to come. Their attention to detail, communication, transparency, and fair pricing has made them my go to recommendation for anyone looking for a special piece of jewelry for their loved ones.
The ring is perfect!
Had a few little worry’s to begin with but the staff were amazingly helpful! I received the ring in the delay time they stated and the ring is absolutely beautiful!! I cannot wait to propose to my future wife with it!!
Thank you all for the help and quick responses to my emails!

Another memorable experience with Diamondere
I’ve worked with Diamondere on multiple custom pieces over the years, and my most recent experience truly stands apart.
This ring marked a deeply personal milestone for me—turning 60 and completing my doctorate—and it was over 20 years in the making. I wore it for the first time during my dissertation defense, and it felt exactly right.
The craftsmanship is exceptional. The diamonds are beautifully matched, radiant, and balanced across the band. What surprised me most was the inclusion of 21 individual GIA certificates—one for each stone—which reflects a level of transparency and care I had not experienced even in my prior purchases.
Throughout the process, the team (Meghan, Diana, Cherie, and Jay) communicated with honesty and integrity. At one point, they chose to remake the ring at their own expense because it did not meet their internal standard. That decision alone speaks volumes about their values.
This was not just a purchase—it was a collaboration and a meaningful life moment.
I wear this ring daily now as a reminder of the journey it represents.
I’m grateful to Diamondere for the care, craftsmanship, and consistency they’ve shown me over the years. In a world where jewelry can feel transactional, this felt deeply personal.
I recently purchased a Eugene…
I recently purchased a Eugene engagement ring, which I was able to design and personalize myself. The entire experience was positive from start to finish, thanks to Cecelia who worked very closely with me. She took the time to chat with me via telephone, text with me many times to assure exactly what I wanted was provided, and also assure me of shipment, etc., and even calmed my nerves (!) The ring is absolutely gorgeous! And I am very happy. Thank you again... Now, time to propose...
Multiple Frustrating Issues!
In response to Diamondère's reply to my original review, I will just say this:
1. I do remember your giving me a pair of small, women's diamond stud earrings as "compensation." I have no recollection of this gift card you spoke of. Let's just say, considering I was buying two men's engagement rings, your decision to offer us women's jewelery as compensation was more than a little tone deaf and did nothing to help our situation. As I recall, we gave them to our neighbor's teenage daughter. What good were they to us?
2. I did approve the design of the remake. What I did not approve was getting a diamond that was half the size of the original I picked out. I paid for a 1 carat diamond, which was in my original ring. The remade ring had a diamond half the size in it. You said I could have contacted you again to resolve the issue. What was I going to do, have you make the rings a third time? My partner and I had already been without rings for months at this point. Not only did your carelessness ruin my proposal itself, but then, during the intial weeks of excitement when family and friends asked us to show them our engagement rings, we had nothing on our hands. Come on, guys! Whether or not I contacted you at the time, I can still say that the final product was NOT what we had agreed upon and what I had paid for. You could have seen that youself, if you had bothered to look at them with any care.
3. I wish I could attach a photo of the jewlery to show other potential customers the very substantial band in which the diamond is deeply embedded. That would be more than enough to tell them that your claim of normal wear and tear is really pretty silly.
In any case, I know there is nothing you can or will do to solve the issue now. However, I do wish I had known about these matters prior to deciding to work with your company. I am posting this rating merely as a warning to others.
If you're just buying jewelry for the heck of it, go ahead and roll the dice. However, if I were you, I would not trust this company with an important occasion such as an enagement, wedding, or anniversary.

Original Review:
I have debated writing this, but after repeated frustrating experiences with Diamondère, I feel other customers should be warned before making such a significant purchase.
My experience involved three major issues, which match the negative experiences of others on here:
1. Significant Delays: I went to great lengths to plan and organize what was meant to be the perfect proposal. Because the plans were made well in advance and could not be rescheduled, Diamondère’s multiple delays forced me to propose with a cheap substitute from Amazon. It was really a huge disappointment for a milestone I had worked so hard to coordinate.
2. Poor Quality Control and Design Matching: When our matching rings finally arrived, they did not correspond with the agreed-upon schematic. The bands became ridiculously thin as they wrapped underneath, which felt like a blatant attempt to save money on materials at the expense of the design. While Diamondere agreed to a remake, the second set was even worse. They swapped the perfectly matching diamonds I had originally selected for stones with completely different dimensions! These new stones were much smaller than the originals and did not even match each other, leaving the rings with more gold surface than diamond. Tired of the hassle and the month-long wait times—and not wanting to upset my partner who was already feeling bad about the whole situation—I felt forced to settle for a product I wasn’t truly happy with.
3. Lack of Durability: My partner and I have been incredibly careful with these rings. We take them off for the gym, yardwork, cleaning the house, or any activity that could potentially cause damage. Despite this high level of care, the diamond in my ring has already come loose and rattles in its setting after only three years. This is not a dainty prong setting; these stones are embedded deep in the band, which points to a fundamental manufacturing flaw. I tried to just put the previous frustrations behind me, but this is the last straw!
When I contacted the company about the rattling stone, they expected me to pay again to fix it. Given the design and the price, I expect a piece of jewelry to last longer than three years before falling apart. I mean, wouldn’t you?
An engagement ring should be a lifelong symbol of a happy occasion. Instead, every time I look at the tiny replacement stone (or hear it rattle), I am reminded of a company that failed to meet specifications and refused to stand behind their craftsmanship. I really regret choosing Diamondère for something so important.
Think carefully before you make the same mistake when it comes to your big day!

Absolutely amazing customer service…
Absolutely amazing customer service from beginning to end and the ring & diamond are stunning. Often times it’s difficult to strike a balance between product quality and customer service but Diamondere has done it - cannot recommend them enough!!
Diamondere did an amazing job on my custom order
I recently ordered a very specific custom ordered ring and Diamondere produced a ring better then I could of ever imagined.
First off lets start with how professional and swift all their employees are. I dealt with Cheri and Emma. Emma helped with the design and was wonderful and patient with me as we decided what I wanted to do. Emma gave me numerous quotes in different metals. Cheri ended up emailing me after the order was placed asking about my fiance and Is story how we met and how we found them which I really appreciated and viewed as very professional.
Diamondere is a company I have been recommending to clients for years as I have a background in jewelry sales. So needless to say I was very excited when it was finally my time to purchase one. The quality they produce is wonderful on top of that you get more then what you pay for. I am still shocked at how much gold we actually received on his ring. Their rings are heavy and solid and are priced amazingly. They also do a great job of producing high quality alternative rings. We did 14kt black gold and Alexandrites. Shipping was timely quick and fast. I was provided with a tracking number as well as a requirement to sign before dropping off. If you're on the fence of ordering from them this is me telling you to do it! They will not disappoint you =)
