Hollim27,
The platinum 1895 Cartier Solitaire with sidestones is also my dream, but I consider it an attainable one in that I plan on recreating it with an H&A Amora Gem center and having it put in a Leon. I posted about it in this thread:
Who else has picked out a setting for the Amora gem already?

ETA: I forgot to add the size. Originally I was thinking 8mm/2ct, which is the size Asha I have now, but since finding out that the Amora Gem will be "only" $500 a carat (originally Less was saying "Mira" would be 2 or 3 times the current price of Moissanite, but that's all changed now!), I'm thinking 9mm/3ct! Heck, why not! It's going to be my forever wedding set!
