This is SpaRitual Nail Lacquer in Gilded Age. I'm not sure if this color is available anymore. I bought this from HauteLook a few months ago.
On my toes I have OPI for Sephora in Once a Cheetah, Always a Cheetah.
Once a Cheetah, Always a Cheetah is available at Sephora and is on sale for $4.50 (down from $9.50).
