Jet Black or Polished Black looks great with nearly any lens, but Metallic Black takes this appearance to an entirely new level. As with other metallic finishes, Metallic Black features small specks of aura scattered about the frame. Unlike most other metallic finishes, however, the specks appear to be brighter and more lucent.

I totally agree with EC,
you cant tell from the pictures how nice this frame really is.
its a glossy black with very obvious silver sparkles.
you dont even need to put them in the sun to notice it.
i got these on my eye jacket 2.0 and must be the best colour they come in.

Looks much different in bright light than dark. The sparkles really stand out and make the frame shine. Pictures do not do it justice.
