Sergio was a pleasure to deal with. I sold him my 2 carat diamond engagement ring. Not only did he offer a very fair price, but he was very helpful and thoughtful during the whole process. It was MUCH easier than I ever thought it would be. The payment was made immediately, and I am so grateful for all of his help. I RECOMMEND HIM VERY HIGHLY!!!!

I sold my diamond, almost three carats to Sergio. He was the consummate businessman. He promptly returned my e-mail and phone call. He was honest, ethical, and assuring. I would not hesitate to recommend Sergio to anyone who plans to sell or buy a diamond.

I was very leery about selling a diamond online. I looked at several sites, sent them all the info about the ring, and used search engines to see if I could find any negative feedback. Sergio’s final offer was right in the middle of the range we discussed and it was only a few days from the initial email to depositing the check.

When I decided to sell my center diamond I chose Sergio because I was very impressed with our initial phone conversation.He was knowledgeable and gave me a range for my diamond and explained every detail so that I would know what to expect.Sergio has been uplifting and so kind and supportive even after the transaction in a follow-up phone call.I give Sergio a 10 out of 10.

I met with Sergio at his showroom and immediately felt comfortable with him. The experience, from the time I walked into his office until I walked out with the check, was easy and enjoyable.I will definitely tell other people if they are interested in selling a diamond or purchasing a diamond to contact Sergio!!!
