Diamonds are a girl's best friend, but are they for your vodka? The newest exclusive Slovakian sauce on the market is the premium Double Cross Vodka. It's made quite a splash since it was released in September, winning awards for its taste and unique rectangular bottle design. Filtered seven times through micro diamond dust to smooth out rough edges, this exceedingly pure vodka -- with hints of white pepper and lemon zest -- is exceedingly hard to get your hands on. It's currently available only in New York and New Jersey. Has this luxey liquid indulgence crossed the price line at $50? Let's not forget that the old $13 Smirnoff workhorse, filtered ten times but not with diamonds, won the New York Times' blind vodka taste test out of 21 vodkas -- a diamond in the rough!
