As the managing editor of the New York's Weddings issue, I regularly cultivate my inner bridezilla. I started my search at Cartier, mainly because I’m partial to anything French. The rings here range from just under $5,000 to well into the millions, so it’s easy to lose your head. My favorite was the Declaration d’Amour, a princess-cut solitaire ring with diamonds on either side of the platinum band (1.6 carats; E color). A princess is more or less square, which I always thought would look a little pudgy, but it didn’t. And the 1.6-carat weight was perfect. 635 Fifth Ave., nr. 52nd St.; 212-753-0111.
