A recent color fashion jewelry trend for jewelry is black metal, which has an unconventional but pleasing look. Some gemstones look particularly dramatic when set into black metal.

The emeralds are set in black gold so that the metal takes a backseat and shoulder handbags the bright green emeralds.
