Working by appointment only, this is a trustworthy dealer.  They are extremely patient to hear your needs, discuss prices and design your dream ring.  Their prices are very competitive and they only deal with GIA-certified diamonds.  They even tell you to go with another dealer when they don't think they can match the competitor's price (which happened in my case).

If I were to shop for a ring again, I would go back to them.  They even have a satisfaction guarantee policy-- if your lady does not like the ring, they'll give you your money back (within a couple weeks).  Even if it's a custom-made ring.  Takaki K.  Alrington, VA  2/24/10

My husband and I had a wonderful and satisfying experience at Washington Diamond. This was the 3rd place we went to find the perfect engagement ring for me so going in we were quite leery. We had a really bad experience with Jared where they sold us a stone that after we got it appraised, which we paid for, was valued at half of what we paid for it. When we went to them to rectify the problem they wouldn't pay for a second appraisal and they kept telling us that they were going to stand by their product. Needless to say we returned the engagement ring and cancelled the orders for the wedding bands.

My husband found Washington Diamond online and made an appointment and from the moment we stepped into the showroom we were treated warmly and professionally. We sat down with Tom and he pulled out several stones and even offered to make whatever I wanted. Our consultation with Tom was so educational and professional that we found a setting we liked and purchased a stone that we had not even seen because he had just purchased it and it was coming that next morning but we felt so confident in Tom's word and expertise that we would be completely satisfied with our purchase we agreed to it. And we were surprised. Both of us were so very pleased and stunned at how beautiful my ring looked, even his sales staff was complimenting the ring. The clarity and color of the diamond is exquisite. Its been a year since we bought all our rings and I still get mouth dropping compliments on my set. Thank you Tom and the whole Washington Diamond staff for everything that you do. We tell everyone we know to go see Tom at Washington Diamond, you won't be disappointed. A. Smith - Maryland, April 2010

The best diamonds! No other business compares. Christy M.

When I received it after it was resized, it was indeed different. It turned out better. The new finish is much more durable than the original. Whereas the old brushed finish scratched very easily, the new is bulletproof. And in cutting it down, the cut was placed to remove some of the existing damage on the polished sides. The new fit is perfect as well. Thanks again, Luis

Thank you guys so much. I wanted to let you know that my wife almost fell out of bed when I gave her the anniversary band you helped me with. - Colin
