    This is a very honest and extremely customer centric establishment. In 2007, I bought an engagement ring from Igor for my fiancé with an agreement that if I decide to upgrade he will take this ring and give me credit towards the upgrade. Well fast forward to 2017, Igor not only kept his word, gave me an excellent price for the upgraded ring but also patiently took his time with my wife. We went to him about 5 times and finally he had the new diamond set on a custom made ring based on the picture that my wife gave him. It's great to know that there are still honest people in the diamond industry. Thank you Igor! We will see you in 10 years yet again.

    The wife loves her ring.

    Picking out an engagement ring is never easy. They helped point me in the right direction. They walked me through everything and answered every question I had. They showed me different options and made the whole experience as smooth as possible. I go to them for all my watches and jewelry. Igor and Arsenie are the best. Thank you guys!

    I live in Denver and purchased a Cartier Roadster from Dennis. He sent extra pictures and was readily available to answer questions. He was patient with me as I took several days to decide. I saved $600 and received a like new condition pre-owned watch overnight. Fantastic service and a beautiful time piece from across the country. Highly recommend!

    Where do I start, my fiancé and I plus the children had an appointment with Carlos recently, and to my surprised he was helpful patient with a nice attitude. He took the time to show us clarity in diamonds, ring settings ex(princess cut, cushion cut) and displayed a variety of styles to fit my taste big and small diamonds . He knew exactly what we was interested in. Overall experience with Carlos and his staff was hassle free, friendly and was not trying to kill you in cost . He definitely worked with us which is a huge bonus in these times today . I am going back to pick up my fiancé ring which we will be customized so I'm excited and I recommend you go here for the experience too. Oh btw grab a shot of expresso while there you won't be disappointed- Q

    Carlos is an honest seller. I got my ring out a few months ago, and am still very pleased with my purchase. Thanks again Carlos!

I happened to be in Grand Central Terminal in Manhattan today, so I ran over to Grand Central Watch to get an estimate. I was really upset because my wife bought me this watch on vacation years ago, so there is a sentimental attachment to it. The owner saw that I was stressed out and she looked at it, turned around, fixed it in about a minute and handed the watch back to me. I was really nervous because I didn't know how much it was going to cost. I asked: "How much is the repair?" She replied, " There is no charge. Just leave me a review on Google." I couldn't believe it. I didn't know there was any place left on earth like that. How could I not leave a review after that? Five stars!!!!!!!
