Lauren Sewald

I am absolutely in love with my ring! Riddhi and team were such a pleasure to work with. They made the process of customizing it to the correct gap width so easy and were super communicative throughout the whole process. The ring looks even better than I thought it would and fits perfectly with my engagement ring. I will absolutely come to DiamondsByUK for my next jewelry need!

Melissa

After several years of marriage, my husband ordered a ring from DiamondsbyUK to ‘give me the ring he wished he could’ve given me when he proposed’. It’s absolutely breathtaking - I feel like I’m newly engaged with how I cannot stop looking at my hand smiling. On top of the quality and beauty of the ring, Riddhi and team provide 10 star level customer service! They even wrote a personal card from my husband that was delivered with the ring!! And the ring I’m technically reviewing right now is the customized band that they created to match. They are perfect - more than I could’ve ever imagined. I feel spoiled and blessed - I’m in awe every time I catch a glimpse of sparkle on my hand! I truly cannot express the depth of my gratitude. There are no words for how happy I am with both rings. THANK YOU RIDDHI & TEAM - DiamondsbyUK

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!

I cannot reccomend this seller enough. The ring itself is outstanding and my now Fiance loves it. Riddhi and her team were absolutely brilliant 👏 I needed it for a specific date and they were so helpful in getting it to me. We will definitely be getting wedding rings from here too.
