DREAMY stone, DREAMY setting! Its lines and the stone are simply breathtaking. Count me in with those who regard your ring as a PS fave. Congratulations on your engagement and on creating such a wonderful setting with the ERD guys.
Cynd33 - Size 5. It took a couple of tries to size it. They worried about sizing too small, since my knuckle presented the possibility of stress to the setting over time. However, they also worried about sizing too large, as the ring might slip-slop around my lower finger (which measures at about 4.5) due to the size of the stone. In the end, I went in for a final fitting and we sized down a bit.
Sheer perfection down to the last detail! I am glad that Mark let you in on the design process. It is your piece of ART and you can proudly wear it knowing that you were one of the "designers".
