The Italian titolo is the legal fineness mark struck into precious-metal articles produced or sold in Italy. Unlike the British carat-based hallmark or the older European purity grades, the Italian system expresses precious-metal content as a three-digit number representing parts per thousand, stamped in an oval cartouche alongside a maker's responsibility mark.

Statutory framework

The system is codified by Decreto Legislativo 22 maggio 1999 n. 251 and its implementing regulation D.P.R. 30 maggio 2002 n. 150, which together govern the marking of articles in gold, silver, platinum and palladium. The legislation requires every Italian manufacturer or importer to register with the local Chamber of Commerce, after which they are issued a numeric responsibility mark in the form of a star followed by the registration number and the two-letter province code (for example, a star, the digit sequence and "AR" for Arezzo).

Permitted fineness values

For gold, the standard titoli are 750 (18 carat), 585 (14 carat) and 375 (9 carat). Higher purities such as 916 (22 carat) and 999 are permitted but are uncommon in domestic production. Silver is marked at 925 (sterling) or 800 (the older Continental standard still used for hollowware and ecclesiastical work). Platinum is struck at 950, 900, 850 or 800, and palladium at 950 or 500.

Marks in practice

A finished Italian article therefore carries two punches in close proximity: the oval titolo stating the millesimal fineness, and the lozenge-shaped responsibility mark identifying the maker. The convention dates from the post-war reorganisation of the Italian goldsmithing trade, when Arezzo, Vicenza and Valenza Po consolidated as the country's three principal manufacturing districts. Pieces produced before 1934 may carry the older fascist-era mark or, before that, regional assay punches; these are recognised by Italian customs and the trade but do not satisfy current marking law on their own.

Trade significance

For dealers handling Italian chain, hollow-rope work and Vicenza-made findings, the titolo is the primary verification of declared fineness short of destructive assay. The mark is legally a self-declaration by the maker rather than the result of independent assay (Italy did not adopt a state assay office of the British type), so reputable trade practice is to spot-test or XRF-screen incoming Italian goods on receipt rather than relying on the punch alone.
