I had a great experience with Washington Diamond (WD). Tom Daube was extremely easy to work with and I felt I could trust him. I never felt like he was trying to push me into buying anything. He showed me what to look for and guided me as to the important and not so important things about diamonds. We also compared prices of WD with online jewelers. I would recommend Washington Diamond because I feel that I can trust that they are not just into selling a diamond, but also educating and letting the customer feel comfortable about their purchase.
