I had the best experience at Diamond Banc! She usually only accepts appointments but took me in with no question which I thought was so nice. Then she was able to give me an appraisal and paid on the spot. By far most professional jewelry appraisers I’ve experience and would completely recommend 10/10! ❤️ she will always be my go to girl for the future.
