Kristen Bell's bold and chunky Bulgari necklace suited her upswept do and flowing Jenni Kayne maxidress. You can get a similar (but more delicate) look with Busarin's Jungle Stars, a citrine and tiger eye choker. (Buy Direct).
Badgley Mischka's Crystal Cluster Necklace offers a very similar look to the one Kristen is wearing, but at $300 is more expensive than the other alternatives. (Buy Direct)
