What does 750 Italy mean on jewelry
With 750 Italy, ITALY is a separate country-of-origin inscription. A plain 750 fineness mark describes the gold alloy.
750, 18K and neighbouring stamps
750, 18K and 18CT express the same gold proportion: eighteen of twenty-four parts. Yellow, rose and white gold can all carry 750 because the number describes gold content, not colour. Common combinations include 18K 750 and 750 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: 18K GF describes a gold-filled layer and 18K GP a plated layer. A plain 750 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.
