What Our Customers Says

I choose to use DiamondsbyUK in my search for a wedding band, and I absolutely LOVE how mine turned out! It was the exact design I was looking for, and the specs are wonderful (about as good, if not better than what I would have gotten at a jeweller, for a better price!) I have gotten so many compliments on it and am so happy I went with this company! Their customer service is phenomenal and is very communicative with the process and any questions/ concerns you have.

The one ring. The ring of rings. It’s perfect. It really is stunning. Genuinely, I Can’t wait to put it on my partner’s finger and see the look on her face! Riddhi and her team have consistently communicated with me throughout the process! Will be back soon to organise another ring for me for the big day! Thank you so so much to you and your colleagues, Riddhi.

I’m so glad I trusted the reviews and decided to order from DiamondsbyUK! I was a bit hesitant at first about buying expensive rings online, but the number of photo reviews and the consistent praise for quality and service convinced me to give it a try. Even the very few neutral reviews still said the rings were beautiful — and they were absolutely right. I ordered 4 rings and every single one is stunning. The craftsmanship is excellent, and the overall experience exceeded my expectations!

Such a pretty ring 🥰.I recently purchased a ring from this incredible company, and I couldn’t be more thrilled with my experience! From the moment I browsed their collection, it was clear that they prioritize craftsmanship and design. The ring I chose is absolutely stunning—every detail, from the setting to the stones, exudes quality and elegance. It’s evident that the artisans behind these pieces pour their heart and soul into their work. Customer service was also exceptional. They were incredibly responsive and made sure I had all the information I needed to make my decision. The shipping was prompt, and the ring arrived beautifully packaged, with a personal touch that made the experience even more memorable. If you’re looking for a piece of jewelry that combines beauty, quality, and exceptional service, I highly recommend this company.

Everything from start to finish was amazing, Riddhi was so helpful and accommodating for when I wanted to make some changes to the ring design and the end result was the most perfect ring I could imagine. My fiancée loves it, it’s the perfect size and the diamond is amazingly sparkly, everything about it is perfect, thank you so much!!

Me and my fiancé are both very impressed with how this ring turned out! For anyone wondering, yes this ring is legit, I had it taken to a local jeweler and they verified the quality of the diamond and the metal used. Riddhi and her team did an amazing job, and even paid for fast shipping to ensure that it arrived before my proposal date. Could not recommend this company more!

I placed a custom order with DiamondsbyUK for my engagement ring because I wanted to support a UK-based, women-led business and felt confident in the quality of their work from the many positive reviews. Riddhi was great, very patient and did multiple drafts of the design until I was happy, and was also very accommodating of the fact I had sourced my own diamond that would need to be set in the ring after I received it. She was also great at answering any questions or concerns I had promptly. I am very satisfied with my ring! It is high quality and the only minor issue was that one of the prongs was slightly out of line but I thought that this probably wouldn’t be a massive issue because I figured that the jeweller would remedy this when setting my diamond in the ring (which they did). I love my ring, it is stunning!

Getting this ring made was such a pleasant process! When I ordered I just thought a ring would turn up in a few weeks, but I got a custom service where they built the ring around my engagement rings measurements, and I was sent updates as it was created. I even got speedy delivery for free! Thanks for such a great experience

Thank you so much Riddhi and Team. This ring is just beautiful, so incredibly delicate, perfect proportions and has plenty of sparkles due to its excellent cut! Also the little ring box it came in is so lovely, in elegant dark royal blue. I was curious how the engraving will turn out since the ring band is so thin and I absolutely adore the tiny font. The Team seems to be always available, responding fast and patiently. I felt very well supported and informed. I also was gifted free express shipping and the ring was delivered before the expected time frame. Although I got the 0.80 carat, I got a certificate (which is personalised and in a protective envelope). Everything about this order just felt very high quality. So happy!

I am obsessed with this ring. I literally screamed when I opened it for the first time because it was exactly what I was looking for! I was worried that there wouldn't be enough space under the main stone to lay flush against each other but Riddhi was so helpful and customized the ring to fit perfectly with my engagement ring dimensions. After looking at wedding bands for over 5 months, I can confidently say that their pricing is very reasonable especially considering the high quality. I loved that it came with a certificate proving the materials used as well. All in all the ring is even more stunning in person and I cannot wait to get married so l can wear this everyday!! Thank you Riddhi and your team for crafting me the perfect ring for me!

I proposed to my partner with this ring in New York with the intention that this would be a placeholder ring before we came back to buy the real ring, but she loves it SO much that it will be her main ring. Fantastic customer service throughout the whole process with Riddhi and the ring was delivered in time before my trip. Could not have been happier with the outcome and we now have a beautiful ring to remember this special time. Would highly recommend!

My fiancée LOVED her ring. I would encourage couples who are looking to propose to trust this company. I was scared that it would not fit but it was just tight enough to be able to stay in her finger without her worrying about it slipping off. 10/10 quality and 10/10 service!

My experience was great from start to finish. Amazing and helpful team! The team were so helpful in explaining the process to me, giving advice and made the whole process so simple with no stress whatsoever. The ring is absolutely beautiful and so classic. I planned to buy on the high street but it was just expensive and no unique styles, this account uses the same material and sells at a much reasonable price. I’m so grateful for the help and would 100% recommend.

Absolutely thrilled with my wedding ring from Riddhi! The entire process was a joy—Riddhi was incredibly responsive, friendly, and accommodating with every change. Unlike other jewelers who require a mold or your engagement ring, she worked with just a few photos next to a ruler—and the fit is perfect! The craftsmanship is stunning, diamonds are brilliantly sparkly, and the ring even came with a certificate. Riddhi’s patience and attention to detail were exceptional. She provided a new render for every change and only started making the ring once I was 100% happy. The whole experience felt personal, exciting, and far superior to other jewelers I considered. I couldn’t be happier and can’t wait to wear this ring forever. If you’re looking for a custom-made piece with an amazing experience to match, I highly recommend Riddhi!

It was perfect! They worked with me to make sure the measurements of the gap were perfect, and you can’t even tell that there’s a gap from the top. It stays and is flush with my engagement ring. I work in jewelry so normally I get my pieces from my company but I will continue to work with DiamondsbyUK! It’s everything I was hoping for.

The ring is absolutely perfect. The proposal all went to plan and my partner loved it. She enjoyed showing it off to everyone at Glastonbury festival (started on the day of the proposal) and since. This just highlights how incredibly well it was made, durable, yet it maintains a cute and delicate aesthetic.

The ring is stunning and is clearly well-made! The presentation was amazing and the inclusion of a certificate of authenticity was a particularly nice touch. The seller's customer service was stellar, and they were super easy to deal with. The support, attention to detail, patience and kindness was more than I could have asked for - and my ring is exactly what I wanted!! I have recommended Riddhi to everyone I know, and will be back again in the future. Thank you to Riddhi and the team, I am over the moon with my rings!

After a huge amount of frustration where I couldn’t find a wedding ring I wanted in high street jewellery stores. I took my search to Etsy and am so so glad that I found Diamonds by UK. Riddhi was so understanding, kind and helpful. Even when the first ring I ordered wasn’t quite right for what I wanted, the team strived to help me design my dream wedding ring and I am so happy and grateful. The customer service is next level and now have a ring I love and can’t wait to wear on my wedding day. Thank you so much Riddhi and the team.
