I’ve been sporting dark manis all month but I haven’t actually worn black on my tips yet!  Sephora by OPI Never Enough Shoes (Autumn and Eve, Fall 2008) is a black peppered with gold and silver microglitter:

Picture taken in sunlight.  This applied well, needing two coats to be fully opaque.  The glitter in this is very subtle, but I like the effect.  I also like that it contains both gold and silver glitter; it sets this apart from other black polishes with just silver glitter (although I do love those too!)  I paired this with OPI Brand New Skates on my toes.
