Would definitely recommend, great experience.Posted on Ben ClarkTrustindex verifies that the original source of the review is Google. Joseph was amazing so great and personable to deal with I was worried about selling my diamond rings in the UK but I filled out the online enquiry form and Joseph got back to me within a hour quoting a price and I had already done research and enquired other places. Joseph beat them all hands down and not only that was polite to deal with and not aggressive like other diamond dealers he was polite friendly and professional. All his reviews are flawless and he totally lived up to them I felt privileged to have found his website and be able to deal with him. I sold my 2 diamond rings and upgraded them both to bigger stones and the quality of the stones it’s out of this world I’ve always done my diamond dealing in Dubai and Joseph totally beat that whole experience the stones are beautiful and he involved me in the selection process to make sure the diamonds were right. I even wanted a particular setting for the emerald I upgraded to and he made that happen. I can’t explain how happy I am don’t delay work with Joseph whether it’s selling or looking for a new piece he will help you every step of the way.Posted on Josh Chaubert-CooperTrustindex verifies that the original source of the review is Google. I used YL Diamonds to help design an engagement ring as well as trading in another ring. I was extremly impressed with the professionalism of Joseph and his white-glove approach. He really understood what I was looking for and worked closely with me to make sure the finished product was exactly what I wanted. I have dealt with a number of firms in Hatton Garden (with mixed results) and I'm just so very grateful to have found YL Diamonds. The ring is gorgeous and my fiancee was very happy to say the least.Posted on Jorna MiahTrustindex verifies that the original source of the review is Google.
