Vanessa sought out to win her mother’s approval in last night’s “Enough About Eve” episode of Gossip Girl, but little did she know that all it would take is this Aqua Glass Necklace by Siman Tu to win our hearts.

Don’t get us wrong. Vanessa looked absolutely exquisite all dolled up in her classic silver silhouette and deep rouge lips (can you say old Hollywood glamour?). But, as diehard fans of her vibrant, eclectic style, we have to admit that we love to see this girl let her hair down.

With tiers of luminous faceted aqua glass teardrops falling in an elegant, cool cascade, this chic piece is one of the hottest items this brunette bombshell has worn yet. And because we can see this bold embellishment bringing all of our cold weather wear to life, we nominate this necklace as the must-have jewelry item of the season.

Fun fact: Curious to know where you have seen this designer before? Siman Tu also created Lilly’s Blue Turquoise Cabochon Earrings from the “Rufus Getting Married” episode.
