I love blends of blue and green; they make for a wide range of truly unique and pretty colors.  OPI Jade is the new Black (Hong Kong Collection, Spring 2010) is a dusty jade creme:

Picture taken in sunlight.  (I’m really happy the sun came back out so I could take proper pictures of this one.)  It applied well and was opaque in two coats.  Wow, this color is amazing!  I have no dupes for it in my stash.  And this is another one of those polishes I can’t help but stare at.  Really, it took me longer than usual to write this up ’cause I kept stopping to look at my nails.  I paired this with Sinful Green Ocean over black on my toes.
