- Assay office
Assay offices are
institutions set up to assay(test the purityof) precious metalitems, to protect consumers. Upon successful completion of the assay, (i.e. the metallurgical content is found to be equal or better than that claimed by the maker and it otherwise conforms to the prevailing law) the assay offices typically stamp a hallmark, punze (G.) or poinçon (F.) on the precious metal item to certify its metallurgical content. Hallmarking first appeared in Europe in France, with the Goldsmiths' Statute of 1260 promulgated under Etienne Boileau, Provost of Paris, for King Louis IX.

United States Codemakes it unlawful to stamp goods in the United States with "United States assay" or any similar stamp which gives the impression that the item has been officially assayed by the United States government.

There is no hallmarking scheme in the U.S. yet assay offices did/do exist in the U.S. [ [http://www.treas.gov/education/fact-sheets/currency/prod-facilities.shtml U.S. Treasury - Fact Sheet on the Mint and Other Coin Production Facilities of the U.S. Government ] ] but they are affiliated with the government's coinage mints and serve only the government's purposes in that field. Those purposes historically included receiving bullion deposits from the public or mining prospectors in the various American territories in the 1800s. Today, those assay offices that still operate function solely within national coining system (including bullion coinage for sales to investors) but are not involved in hallmarking, the end product of the assay which is the subect of this article. There is no hallmarking scheme in the U.S. However, the U.S. assay facilities include: [ [http://www.treas.gov/education/fact-sheets/currency/prod-facilities.shtml U.S. Treasury - Fact Sheet on the Mint and Other Coin Production Facilities of the U.S. Government ] ]

Dutch (Netherlands) assay office
General overview and function of the Dutch assay office
The Dutch (the Netherlands), who are members of the International hallmarking Convention, have been striking hallmarks since at least 1814, but boast a 600 year history of hallmarking in Dutch territories. Like many other nations, the Dutch require the registration and use of Responsibility Marks since 1797. The Dutch also use a date letter code. After the French defeat at
Leipzig1813 the History of the Netherlands was established. William VI, prince of Orange (known in Dutch as Willem Frederik), was proclaimed the sovereign. On March 15, 1815, with the support of the powers gathered at the Congress of Vienna, William proclaimed himself King William I of the Netherlands. He was also made grand duke of Luxembourg. The two countries remained separate despite sharing a common monarch. For our purposes, he retained much of the French legislation, including the precious metal guarantee law of November 9, 1787. On December 26, 1813 the precious metal laws were however, modified and the French hallmarks, the Gaul cockerels were replaced with Dutch lions. The existing guarantee offices were reopened after re-staffing and the production of the new hallmark dies. Willem abdicated in 1840. As of January 1, 1853 the out-of-date French guarantee law was replaced by a new Dutch law. This law of September 18, 1852, in a modified form (last modified in 1986 as the "Dutch Assay Law of 1986") is in still effective. As a result of the Benelux treaty the guarantee tax was abolished in 1953. At the same time gold and silver fineness standards were adapted to conform to international standards. Also the assaying of platinum was introduced in 1953.
In 1987, the assay system was privatized and since 1988 has been located in only an office at Gouda. The system is overseen by the Dutch Ministry of Economic Affairs which appointed Edelmetaal Waarborg Nederland B.V. as of March 11, 2002. In 1999, the Netherlands ratified the Vienna Convnetion of International hallmarking.
Dutch hallmarks are recognized in Austria, France, Ireland, Portugal, Spain and the United Kingdom without further testing and have also been recognized in Belgium, Denmark, Finland and Sweden, which have voluntary hallmarking systems. All jewelry produced in the Netherlands or imported for the Dutch market must carry hallmarks.
Current assay office

Cyprian assay office
There is one assay office at Aradippou.The Law governing the marking of precious metal articles has been ratified by the House of Representatives in 1991, creating a new semi-Governmental Organisation, the Cyprus Organisation for the Hallmarking of precious metals.

The manufacturer's mark - Consists of the initials of the manufacturer of the article surrounded by a small shield; 2. The fineness mark - The purity of the metal, in parts per thousand; 3. The official mark - the Head of Aphrodite until December 2001 and a ship as from January 2002 denotes that the article is made of Gold, and the fish that the articles is made of Silver. The manufacturer's mark must be struck on the articles by the manufacturer before its submitted to the Assay Office for Hallmarking. The manufacturer may make arrangements for the manufacture's mark to be struck by the Assay Office upon submission of the article to be struck with the approved hallmarks. The manufacturer's mark which is registered under the relevant section of the Law shall include the initial letters of the name or names of the manufacturer and shall be of such design as may be approved by the Assay Office. The standards of fineness of Gold and Silver articles that are hallmarked are for gold : 375,585,750 and 916 parts per thousand; for silver: 800,830 and 925 parts per thousand; no negative tolerance is permitted on the above standards of fineness.
