I bought a tennis chain for my wife's Birthday. Miryam was very helpful with educating me on making the right choice and best chain for my buck. I highly recommend Mr. Alex Jewelers.

Amazing experience at Mr Alex Jewelers. I purchased a Rolex for my wife and the service was outstanding from start to finish. Very professional, honest, and knowledgeable staff. They took their time to explain everything and made sure the watch was perfect. My wife absolutely loved it. Highly recommended!
