Boucher made up for its meager selection of cocktail rings with its color selection: Its only style came in green, pink, blue, or gray. I preferred the multicolored ring, done in freshwater pearl, tourmaline, and sterling silver, but I was worried that the hanging pieces would snag my black satin clutch. Plus, I was surrounded by teenage girls doing Sex and the City impressions, so I hightailed it out of the store. 9 Ninth Ave., nr. Little W. 12th St.; 212-206-3775.
