Hooray! I can always count on WWEPW readers! An anonymous fashionista recognized Emma's necklace as this one:
It's the Kate Spade Mariposa Fleur Blue Wasanabi Necklace!
It retailed for $250, and there is ONE for sale right now on eBay for $106. Emmaphiles, ready your clicky fingers if you want this necklace!
Thank you so much to the person who IDed this necklace for me! Please let us know who you are so we can applaud you!
