I recently purchased a Rolex timepiece through Blue Diamond via website and then telephone. Everyone I worked with throughout the process was courteous and knowledgeable, making me feel reassured throughout the sales process. During the final details of the transaction, Nancy was instrumental to ensuring I received my piece in the timeline I needed to, and was an absolute joy to interact with. I’m already considering my next purchase through Blue Diamond and will be contacting Nancy for assistance in selecting the perfect piece. Thank you all for a wonderful experience.

I am overdue in writing this review. I have visited this location twice. Both David and Rick were extremely helpful, and educational about determining the value of certain pieces. I appreciate that they each took their time to carefully evaluate the items. I believe that their offers are a fair market value if you are looking to sell jewelry, coins or flatware. Highly recommend.

This location honor and respected my pieces with fair offers. The customer service was wonderful as well felt very welcomed and was explained the process which helped the process. Im very thankful for having taken the time to make my way there. I would highly recommend this location, best in town!

This place is great! I'm helping clients with an estate sale and took a number of items in to evaluate whether the items were authentic silver or precious stones and the team of Jim and Nathan were just awesome! They made a fair offer to buy on the spot or to come back after meeting with my clients. I highly recommend anyone buying or selling to go to Blue Diamond!!

Such a wonderful experience, David extremely helpful and super knowledgeable. I highly recommend you come in ask for David Jim as well is very knowledgeable with watches Rolex particular in my experience and Adam as well. The hospitality is top-tier complementary drinks as well as top-of-the-line services. My payout was tremendous and they taught me so much that I thought I already knew if you’re looking to sell by trade this is your place by far the environment and atmosphere are spectacular.

I went in to sell my 2 kilos of pure silver Adam and his team gave me a very honest deal. They are very professional and I would definitely use them again, infact I brought back some of my grandmother's beautiful native American jewelry squash blossom necklaces and a Conchords belt. Adam specializes in southwest American jewelry and gave us an honest deal. Yes I would recommend them in the future.
