HEADING NORTH: Mexican jeweler Colette Steckel has crossed the border with a new namesake Los Angeles store on Melrose Place. "I thought Melrose Place would fit me because it is all big designers, but at the same time not massive designers," said Steckel, who is known by her first name. "I don't pretend to be massive. I like to keep it a couture thing." She has invited longtime celebrity customers such as Salma Hayek and Jessica Alba, as well as more recent fans, including Ana Ortiz, Sara Ramirez and Katherine Heigl, to a party last week to celebrate the opening. Steckel stressed that the 600-square-foot store, stocked with 700 pieces retailing from $500 to $75,000, has jewelry for a variety of tastes. "I hate not to have the right thing for everybody. Let's say you are a small person and you hate big jewelry, but you love my style. If I can't give you anything, it is too frustrating," she lamented. Steckel will return to Mexico City, home to her flagship, for her next store at upscale shopping destination Antara.
