I can’t thank this shop enough. They made me a beautiful ring and even fitted my own blue topaz into it for me. It’s a perfect fit and beautifully made. The costumer service is excellent with great communication from start to finish. I would highly recommend them .

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!

Riddhi and the team were an absolute amazing support when I had several request to amend the design. German custom was a pain but I had nothing to do singe the team handled everything with UPS so well and I was always kept in the loop. Would defintely recommend and buy again. 10/10 for the quality of the ring. It was a gift to myself and I am more than happy :)

Only giving 5stars because I can't give higher. Riddhi and her team were fantastic from the start of the process. They went the extra mile to reassure me and keep me updated as they worked on the ring safe to say my Fiancé loves her ring, we even had to resize the ring, Riddhi and team made this so simple.

My husband bought me this beautiful cluster ring and band for our anniversary. My original wedding rings were stolen and my husband replaced them on our anniversary. I absolutely love them and they are the best wedding rings I could ever wish for. The rings are stunning and look extremely expensive. The big diamond in the middle and smaller diamonds on the sides look so classy and elegant. My husband requested the band to be created to match the main ring and it matches perfectly. The rings are comfortable and can be worn all the time and compliment everything I wear. The Main ring is platinum and the band is white gold; the weight of the platinum ring shows the quality of the ring. It is not too heavy at all and feels great to wear. Great ring and would recommend to anyone looking to buy a wedding ring.

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 ordered a travel engagement ring (lab diamond) and wedding band from Riddhi - and both are spectacular! Don't tell my husband, but I actually prefer to wear Riddhi's engagement oval. It's sparkly, it fits my finger beautifully, and I love how it stacks with my other Riddhi wedding band! I will definitely be ordering more from her in the future. (Size 8, 1.5 carat center for reference)

I asked Riddhi if she could make a couple of very minor alterations to this beautiful ring design and she was happy to do so. She replied to all of my questions and messages in good time and nothing seemed to be too much trouble. When the ring arrived it was exactly what I had wanted and matched the description and 3D designs that she sent to me. I cannot stop looking at it. The craftsmanship is stunning! I thoroughly recommend this small (but clearly very busy) business.

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!

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 couldn’t be happier! Riddhi made my engagement ring and my fiancé raved about the service - and I of course LOVE my ring - so I got in touch about my wedding ring. 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!
