When Kelly Osbourne decided to dress up for the Emmy Awards, she planned for a dash of extravagance. The singer-actress, also the daughter of rock legend Ozzy Osbourne, adorned her nails with a one-of-a-kind black diamond nail polish by Azature, a Los Angeles based luxury jeweler. Created from 267 carats of crushed black diamonds, just one bottle of this nail-polish has been created so far, of which, Jennifer Lopez has had a nails done previously. Priced at a whopping $250,000, the nail polish is one you probably wouldn’t want to wipe away after a night out. The nail polish is also the most expensive in the world, and for those who prefer spending their money on stuff other than expensive accessories, Azature has rolled out a $25 bottle that gives a similar shine, sans the black diamonds.
