W's editor posted fashion items that influenced Kristen Stewart's photoshoot in the upcoming September issue of W. Note the word "influenced" unless you just have that kind of cash to get the originals.
"Get Kristen Stewart's Anna Karina meets Brigitte Bardot look from September's "Woman on the Verge," shot by Mert & Marcus."
One of the items noted is a ring by Tiffany & Co.:
"Jean Schlumberger for Tiffany & Co.’s 18k yellow gold, platinum, blue tanzanite, and diamond ring, $60,000"
