What does 585 ITALY mean on jewelry?

Short answer

585: 585 parts per thousand gold (14 karat). ITALY is a country mark: it says where the piece was made or imported from, not what the metal is. The number carries the fineness.

A mark is a statement, not proof: it can be forged or struck on a plated piece. An assay confirms it (touchstone and acids, or X-ray fluorescence).
