As a measurement of purity, 750 fine gold contains pure gold in 750 parts and other base metals in 250 parts. This measurement means that 750 fine gold is 75 percent gold. Although the purity of gold is measured by karats in the United States and the United Kingdom, there are many European countries using the decimal system to indicate the parts per thousandths of pure metal for silver, gold and platinum alloys.
