Dear Interested Izzie
Those necklaces are fabulous. They are made by a girl named Jennifer Meyer (who also happens to be Tobey Maguire's girlfriend) and cost about $1,350. Me and Ro makes something similar for a little bit less money and Maya Brenner has a similar style for even less money - (I particularly like The Watch Over You necklace). For many, many more similar styles, Shop Intuition.
