I am very intrigued by a photo of a necklace in the Cynthia Rowley fall 2010 show. It looks like a piece of rippled, multicolour fabric, worn open in the front.  You can see it in this (sorry very small!) picture:

I love how it has volume and texture but is still quite light. My guess is that it may end up for sale on her web site, as this is a runway piece that is still available there for $275. Made of gold metal and black plastic wishbone forms.
