She is amethyst and pearl

I heard this beautiful song on the radio the other day and thought I knew who was singing. When I heard it the second time I went to look for a video and was surprised by the actual singer. I thought it was Paul Simon.
I couldn't manage leopard skin, juniper, rose or lace, my best attempt at amethyst and pearl, with zebra skin in the background.
The photo has a flare on the necklace, I would have reduced it, but I'm don't know how to using lightroom or picasa. any advice welcome.
