I had to get a link taken off my watch and a engagement ring sized , Yuhan helped me out he was very professional and very patient told me exactly what he was doing with the watch and also with the ring . The prices were very fair and the ring came out sooo beautiful looks brand spanking new! I'm excited to pop the question Tomorrow on the 4th!!! Thank you Yuhan for everything I will spread the word about how great you treated me and how friendly your service was....
