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 Cyprus Assay Office (CAO) is under the jurisdiction of the Ministry of Commerce, Industry and Tourism. 
The Cyprus Hallmark consists of three compulsory symbols: 1. The manufacturers 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 article is made of silver. The manufacturers mark must be struck on the articles by the manufacturer before it is 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.
