Our experience with Diamond Banc was very positive. The process was as secure as possible, the information was timely and accurate, pricing was fair based upon wholesale market factors, and it was executed smoothly. We would happily do business with them again.

Katie was absolutely amazing, and I couldn’t have possibly asked for a better experience selling my Patek Phillipe women’s watch. I spoke to buyers all over town, but went along with Diamond Banc solely because of how attentive, prompt, consistent and the exceptional customer service that Katie provided. She is extremely dedicated, and I am so grateful to have gotten her assistance with this experience. Thank you Katie!

Had a great experience with Katie! Diamond Banc is A1, service wise from Katie and staff and the whole experience in general. Highly recommend and best place to go to in the area, especially with so many other places in the area (1) paying weak (2) having sub par service.

I had an exceptional experience with Katie Diamond Banc during a moment of real crisis involving an extremely high-end piece of jewelry. From the very first interaction, she brought a rare combination of professionalism, clarity, and genuine compassion that immediately put me at ease.

Katie is not only a highly skilled gemologist, but also someone who communicates complex information in a way that feels simple, transparent, and reassuring. She spelled everything out clearly, made the entire process effortless on my end, and handled every detail with precision and care.

Beyond her expertise, she is truly a remarkable person—warm, funny, compassionate, and deeply intuitive in how she supports her clients. In a stressful situation, she made everything feel grounded and manageable.

She is, quite honestly, a gem in every sense of the word. An angel in her field and a true master of her craft. I cannot recommend her highly enough.

I had the best experience with Katie! She was so knowledgable and helpful, and provided transparency throughout the process. I sold a number of 14k gold pieces, and some diamond studs, and felt the pricing was very fair. I will happily be back for any of my future jewelry selling needs!

Katie made me so at ease. She was so informative, kind, compassionate and I just wanted to do business with her considering an emotional and financial decision. It never felt transactional. So grateful!
