I adore this Cartier Panthere ring worn by Rachel Zoe and Kristen Stewart, and it will cost you an arm, a leg, and probably your first born child. (Photo credit)
Love the style of the gorgeous panther ring? Shock Boutique has an incredible look 4 less - it retails for a very budget friendly $30 and you can click here to purchase. (Reader CG found an inspired by option as well - click here to view.)
*Update - 1/3/11* - Bebe added a very similar panther ring to their website, retailing for $19. Better hurry, only a few sizes left (sadly neither are my size)! Click on the photo below if you're interested in purchasing.
