We all remember the beautiful FENTON/FALLON for J.Crew Carrington necklace that our first lady wore for the December 2009 issue of Glamour magazine. Now just about one year later, J.Crew has once again teamed up with yet another stand out jewelry designer for the Winter season–Lulu Frost. This collection boasts geometric shapes and hand-set glass stones a throwback to the art-deco style jewelry of the 1920s and 1930s with a modern twist. Some pieces are convertible going from a long necklace to a choker. As a big fan of J.Crew jewelry, this collaboration is my favorite, it builds a bridge between two different time periods in fashion, then and now, both of which invoke glamour. The collection consists of three necklaces, five bracelets, and two earrings. Here are my picks from the collection. Visit the site to see it in its entirety.
