I shopped around at a dozen chain and local jewelery stores and looked at bluenile as well. I found Washington Diamond to be the best blend of value and customer service in the area. While the diamond prices are the best in the area, they are still a bit higher on average than Bluenile. However, a little negotiation and knowing exactly what you want and what you are willing to pay will get you the best deal.
The ring I purchased is a hand made setting, with additional custom modifications requested by the bride to be. Everyone was very professional, helpful, and knowledgable, so make sure you do some homework before you complete your transaction.
