Thanks everyone!
Bentley1 & Honeybeez, the micropave is quite beautiful but was not my initial choice until I saw it in person. I've always been attracted to an emerald cut so I asked HW if they have one in the micropave design. I was so excited when they told me that they did, but I didn't get to see or try one in person. They did have a pair of earrings in the micropave setting though so I got to put that on my hand and used it as the reference. Also, I did get to see the diamond that they were going to use on my ring so I got a feel of how it would look.
My diamond is a 2.5 carat E VVS2. She is a beauty!
Manitoba, Kohl is right. Although, I was drawn to the emerald cut, I did look at the cushion ones as well. I do recall the 1 carat or so was in the lower to mid twenties and there is room for negotiating.
