Overall, I had a great experience working with TNS Diamonds and Austin specifically. I had a Rolex I was looking to sell and TNS offered me the most competitive price among a number of offers I had received.

Austin was a pleasure to deal with. I entrusted him with replacing my wife’s wedding ring even though I live half the country away. Austin listened, gave me options and helped me pick out the perfect diamond for my wife. All without meeting him in person.I will refer anyone who needs fine jewelry to TNS in the future. Thanks again!!!Zach

I decided it was time to sell my watch so when I Googled to find out who purchased used watches, T&S came up as one of the local options. There were many others but after reading all of the fantastic reviews, I decided I would do business with T&S. I was extremely happy with my decision. Austin was quick with responding to my various texts and had everything lined up so that when I entered the store, it was a seamless process. Austin's Dad was nothing but professional and helpful as well. I do not always write feedback but it was a very positive experience - please check out T&S if you are looking to sell or purchase watches and/or jewelry. You will have a great experience!

I had a superb customer service experience at TNS Diamonds & Watches.I took a wide range of watches to TNS Diamonds for various services (e.g., full service, appraisal). Austin was super helpful and recommended only the necessary services for each watch. He also spent a bit of time with me to explain the services and what was done. Working with him was incredibly easy and seamless, and the service I received was top notch.I will go back for all of my watch service needs, and cannot recommend TNS highly enough.
