Mary-Kate and Ashley Olsen's clothing line, Elizabeth and James, branched into fine jewelry beginning in Fall '09. Now, the sisterly duo has released its Spring fine jewelry line, which consists of two categories: the bar, a continuation of Fall '09's feather design, and the art deco-inspired crest category. Materials such as solid sterling silver, oxidized silver, 14k gold accents, pave diamond accents, and sapphires are used. Retail prices range from $55 to $1,200, the average price being around $200. The sisters are continuing their partnership with Robert Lee Morris — he is their primary jewelry mentor — but since they have taken a more active role in designing, Robert's name has been removed from the brand.You can buy the new collection at neimanmarcus.com (not Neiman Marcus stores), saks.com, Shopbop, Bloomingdale's, and bloomingdales.com.
