#1 Diamond Source 215 East 80th Street, Manhattan, New York 10075

"Hands down the most professional and helpful couple I have ever met! Ron and Lois were extremely knowledgeable about every aspect of the diamond selection, from the cut to the clarity, and assisted me in selecting the perfect diamond, while making the whole experience painless and enjoyable. The added benefit was the custom band that they created to support the diamond, which was everything that my fiancé wanted and more. The ring is spectacular and I would recommend them to anyone who is looking to build a custom engagement ring!"

"Ron and Lois are the best! I researched buying a 30th wedding anniversary diamond ring for months. I considered rings in both Tiffany's and Cartier, but I knew that I would pay a premium for a conflict free, good quality diamond. Then, I stumbled on #1 Diamond Source because of their BBB rating which is very good. I was very nervous about purchasing a diamond in the diamond district but Ron and Lois were knowledgeable, trustworthy and personable. They made the experience wonderful and I have a beautiful ring that was made with care and quality. I will definitely use them again ."

"I was referred to Ron by my brother-in-law. He used #1 Diamond Source for my sisters ring and it turned out great. I couldn't be happier with how helpful they were or how reasonably priced they are. Most importantly I am absolutely thrilled with the ring they made for me! I was pretty specific with how I wanted everything done; from the cut, to the setting and even the design. Ron turned my vision into an amazingly beautiful ring! I live in Indiana and his methods of contact and shipping worked out flawlessly. My fiancé loves her ring and I would 100% recommend #1 Diamond Source to anyone interested in looking for an engagement ring!"

"I worked with Ron to design my wedding band after my husband got my engagement ring from Ron. Ron was patient, helpful and most importantly, genuine and trustworthy. The turnaround time was also extremely fast and the wedding band came out exactly as I wanted. Ron kept me well informed of status at all times and was always timely with returning my calls and emails. Working with Ron was a pleasure and I will certainly be using him again for my precious stone & fine jewelry needs."

"We had an excellent experience with Ron at #1 Diamond Source. My fiancé got my engagement ring from him, and was able to get me the ring I wanted with such great quality. I get so many compliments! Ron worked with us to get me the matching design I wanted for the wedding band at a fair and reasonable price. It is difficult to find people who are fair and honest in this industry so we were happy to do business with Ron and look forward to working with him again in the future!"
