Polish Hallmark
Polish Hallmark
The official precious-metal purity mark issued by Poland's state assay office
The Polish hallmark is the official precious-metal purity mark applied by the Polish State Assay Office (Próbiernia Państwowa) to gold, silver, platinum, and palladium articles meeting the regulatory weight thresholds. As a signatory of the Vienna Convention on the Control of the Fineness and the Hallmarking of Precious Metal Objects, Poland's marks are recognised across the participating European jurisdictions, and the hallmark functions as the country's principal consumer protection in precious-metal trade.
Fineness designations
Polish hallmarks indicate fineness in parts per thousand, following the European convention. For gold, the standard fineness levels marked are 999, 960, 750 (eighteen carat), 585 (fourteen carat), 500, 375 (nine carat), and 333 (eight carat). Silver is marked at 999, 925 (sterling), 875, 800, and 750. Platinum and palladium are marked at 950, 900, and 850. The numerical fineness is the most prominent element of the hallmark, accompanied by a city or assay office identification mark and, in some periods, a date letter.
Mandatory marking
Mandatory testing and marking apply to articles above weight thresholds set in the Polish Hallmarking Act. For gold, the threshold is approximately one gram; for silver, five grams. Articles below the threshold may be marked voluntarily but are not required to carry the official mark. Imported articles bearing recognised foreign hallmarks under the Vienna Convention are accepted without re-marking; articles from non-Convention countries must be re-tested and marked by the Polish office before sale.
Historical background
Polish hallmarking has roots in medieval guild regulation but the modern system traces from the post-1918 reconstitution of Polish independence and was reorganised after the Second World War. The current administrative arrangement, with regional assay offices reporting to the central authority in Warsaw, dates to the post-1989 modernisation of the Polish trade-regulation framework. Poland acceded to the Vienna Convention in 2005, formalising the mutual recognition of its hallmarks across the participating European countries.
Reading a Polish hallmark
A complete Polish hallmark consists of three principal elements: the fineness numeral inside a shaped cartouche, the assay office mark identifying the regional office that performed the testing, and, where applicable, a date or maker's mark. The cartouche shape and the office identifier vary by metal — gold uses a different outline from silver — and reading the full hallmark requires familiarity with the published Polish reference. The Polish State Assay Office maintains a public catalogue of current and historical marks for trade and consumer reference.
In the trade
For dealers buying or selling Polish-made jewellery, the hallmark is the primary verification of metal content and the basis for valuation. Older Polish marks, particularly pre-1986 issues, are sometimes encountered without complete identification and benefit from reference to the assay office's historical catalogue. Restoration or repair work generally requires re-marking by the assay office once the article has been altered.
