These differing carat weights became legal in 1854 for the simple reason that gold before this date was considered a symbol of wealth with 22carat and 18carat. However the jewellery industry wanted to expand their market and started to produce 9, 12 and 15 carat so that the working/middle class could also buy jewellery as well. However in 1936 the government decided to scrap so many different purities of gold and just keep 9 carat as this was the most popular.
