Help with neckace and earrings! (Poll Included)

I am having my necklace custom made. I want it to be shaped like one these:



However, my necklace will have a diamond on the top, aquamarine in the middle, and blue topaz on the bottom (those are the birth stones of the month we are getting married-April, my birthstone for March, and FH birthstone for December).

Which one do you feel is shaped better?

My second question is, what color studs should I get if my choices are one of those stones?

I like the shape of number two the best. I LOVE the significance of the stone colors. I would go with diamond studs.
