Yongjia Sollers


” I just sold my old engagement ring to Jonathan and I am very pleased. Jonathan is honest and trustworthy, I feel being in good hands working with him. He cares about his clients and relationships. He offers the customers the best. I am looking forward to coming back to Jonathan for future deals and highly recommend him!”

Steve Martucci


” This place was GREAT! Jonathan exceeded expectations — he knows diamonds, has all of the tools and connections that are top notch! Evaluated my diamond, tested my diamond and shared the entire process with me. His approach, process and transparency is exactly what the GIA Institute said I should experience and cautioned me about the traps of NY Diamond Market. I did not get lucky with Jonathan with others recommending him to me it was an easy, pleasurable and rewarding experience. Simple, honest and easy — at a minimum you owe yourself to give him a call if you are buying or selling a diamond — he is a cut above! Highly recommend.”

Yoadelys Carreras


” I found Diamond Buyer NYC. Jonathan sat down and explained my ring’s worth. He even price matched someone else’s offer and gave me a little bit extra. Jonathan gave me a fair deal and I will be back to sell more old jewels. He was pleasant and his expertise was superb!”
