The world's most expensive nail varnish

Behold - the world's most expensive nail varnish. This little pot of black varnish which contains actual diamonds costs $250,000. No seriously!
It has beaten Model's Own who previously held the record for world's most expensive polish with their diamond encrusted bottle which retailed for $130,000. This is insanity. Why would you waste so much money!!!!
As you can see - the brand are called Azature and the color is black diamond (duh) - and if you have a spare $250,000 lying around then this could be yours...
