I was a diamond novice looking for a special stone for my wife.  I searched online for a loose diamond and ended up making my purchase from Washington Diamond.  They came highly rated and I was not disappointed.  I worked with Walter Via who patiently took the time, both in person and by email, and provided the information necessary to help me make an informed purchasing decision.  I never felt sales pressure.  Washington Diamond prices were very competitive with online direct sellers and I could physically see the stone prior to purchase. I would highly recommend Washington Diamond.  Scott R. Manassas, VA  6/3/09
