InStyle's editorial guidelines Published on October 8, 2014 @ 04:01PM Pin Share Tweet Email One of the many reasons we love Shailene Woodley is that she doesn't quite fit the Hollywood mold. A self-professed naturalist, the 22-year-old has spoken freely about her all-veggie diet, crashing on friend's couches between films, and making her own toothpaste. So it comes as no surprise that, when it comes to accessorizing, the actress prefers to keep things simple and streamlined. Ergo, she's been spotted all around town (and we mean all around) sporting the same piece of jewelry around her neck: a JLynn Jewelry birthstone circle necklace made of citrine, the gem associated with the month of November (her birth month!). “Wearing your birthstone connects you to a stronger sense of self,” designer Jennifer Lynn told InStyle. Citrine symbolizes strength—so fitting for Woodley, who plays a determined girl on the run in the upcoming film The Divergent Series: Insurgent. And if you want a go-to piece to call your own (drumroll, please), Woodley's necklace can be yours! We partnered with JLynn Jewelry to give away one birthstone circle necklace (in your birth month) to TEN lucky readers. To enter for a chance to win, snap a pic of yourself wearing your birthstone, and tweet it to @InStyle with the hashtag #instylebirthstone. You have until Nov. 13 to send in your entries, and winners will be selected by Nov. 19. Go ahead, show us your selfie.
