You know how celebs like Jennifer Lopez, Keira Knightley, Amanda Bynes, and Rachel Bilson all have that cool, layered necklace thing down pat? The ease is no coincidence. It is actually LA jeweler Shari Wacks.

Shari designs "color stories" which make layering her pieces super duper easy. So no, stars don't just have a magical touch when it comes to this stuff. It's as easy as picking up a couple of Shari's pieces in the same color story and throwing them on.

The designer's CP4 necklace is a favorite of Mischa Barton's and was featured on the pages of Life & Style and People. So we scoped it out to see what all the fuss was about and if the layering thing comes as effortlessly as Shari claims.

First, from one yogi to another, we fell head over heels for the cute Ohm coin while the bright lapis star made us feel happy inside. Second, the 17" inch chain was the perfect length, period. Third, yes, the layering is as painless as Shari says.
