I definitely vouch for Washington Diamond and Walter!
We arrived early and were seen right away. We were shown three sapphires that were currently available and I chose one with the color I wanted. They had all the settings on the website available for viewing as well. I went with my favorite which is always a good choice and couldn't be happier. Walter even negotiated the price for us to get us an even number. The overall experience was very stress free for me and my fiancee. Very happy with our purchase!
