World's Most Expensive Nail Polish

Here is a peek at the world's  most expensive nail polish courtesy of Los Angeles based luxury jeweler Azature.  It features 267 carats of real Black diamonds.  Only one bottle has been produced.   Kelly Osbourne has worn the polish (no need to apologize Kelly!)  For those of us on a budget the makers have been so kind to make a smaller 0.5 oz for $25 a bottle.  Wonder what the tip would be for a $250,000 Manicure?
