Sparkle, sparkle and more sparkle.

The J. Crew shop on New York's upper Madison Avenue was transformed into a sparkle emporium Thursday evening as the retailer celebrated its collaboration with jewelry company Lulu Frost. The gorgeous bling-y pieces took center stage in display cases, sprinkled on merchandise tables and, of course, on the festive party-goers, who seemed to be buying the necklaces and bracelets in bulk.

"It's been a long time coming," Lulu Frost's Lisa Salzer admitted to StyleList. "I think [J.Crew women's designer] Marissa [Webb] bought a piece from a little eco-boutique and the conversation started." She added, "I'm a huge fan and I always have been. Once the idea was born, we went through my archive of pieces that represent my aesthetic and added the little twists that make it J. Crew. It's been a great learning experience."

Working with both Webb and J. Crew president Jenna Lyons was definitely a learning experience. "They're amazing people. Even in the face of huge responsibility, they have a great sense of humor," Salzer said. And Lyons can't get enough. "Jenna likes layering – always more – diamonds mixed with costume – that high-low mix. It's what J. Crew is about – being casual and American, with a luxury element." And balance that Salzer worked into her personal Spring 2010 collection with porcupine quills, gem stones and unique vintage pieces.
