What does 585 Italy mean on jewelry
With 585 Italy, ITALY is a separate country-of-origin inscription. A plain 585 fineness mark describes the gold alloy.
585, 14K and neighbouring stamps
14K 585 combines karat and millesimal descriptions of the same grade. 14/24 is 58.33%; 585 specifies 58.5%. The closely related number 583 expresses 58.3%, so retain the final digit when copying an older stamp. Common combinations include 14K 585 and 585 ITALY. Look inside a ring shank or on a chain clasp or end tag. An Italian identification punch can also contain a star, a registration number and two province letters; that registration number serves a different role from the fineness.
What to check next
Keep suffixes attached to the number: 14K GF describes a gold-filled layer and 14K GP a plated layer. A plain 585 fineness mark describes the gold alloy. On a chain, inspect the links as well as the clasp because a replacement clasp can carry its own stamp.
