Gold alloys

Gold alloys – differences between different countries

• Germany: In Germany, the standard gold alloys used in the jewelry industry are 333 gold, 585 gold and 750 gold (crown gold). The highest quality of these is the 750 gold alloy, as it has the highest fine gold content at 75%, but still has a sufficiently large proportion of alloy partners to be easy to process. Gold bars used for investment purposes must have a fineness of 99.9% in Germany.
• United Kingdom: The most commonly used gold alloys in the UK have finenesses of 37.5%, 58.5%, 75% and 91.6% respectively.
• France: In France, the gold alloys 750 gold, 840 gold and 920 gold are common. The type of stamping differs from that in Germany: gold with a fineness of 92% is stamped in the form of a man's head in conjunction with the number one; a fineness of 84% is marked with a man's head and the number two.
• Switzerland: In Switzerland, 750 gold alloys are commonly used in jewelry. If the fineness is less than 37.5%, the goods may not be sold under the name gold.
• Italy: In addition to the German gold alloys, there is a 900 alloy in Italy, which is also known as coin gold and is minted with the head of Jupiter and a one.
• India and Thailand: These two countries are notable for the fact that gold alloys with a very high purity are used for jewellery. In India, the gold used as standard has a fineness of 91.7%, in Thailand it is 96.5% ( Thai gold ).
