I love when rich, dark colors are also sparkly; I think they really suit the holiday season.  OPI Holiday Glow (Holiday Wishes, Holiday 2009) is a chocolate brown with gold and rose microglitter:

Picture taken in natural light.  This applied well; because of the sheerness of the formula I needed three coats for full opacity.  But the sheerness is what makes it a great base for the microglitter.  I love this unexpected combination of colors!  It makes me think of raspberries and chocolate (wrapped in gold foil)…yum. 🙂  I paired this with Orly Golden Maharaja on my toes.
