Fineness Wikipedia

For example, a gold alloy of 127 ⁄ 128 fineness (that is, 99.2% purity) could have been described as being 23-karat, 3-grain, 1-quart gold. The karat fractional system is increasingly being complemented or superseded by the millesimal system, described above. Conversion between percentage of pure gold and karats: 58.33–62.50% = 14K (acclaimed 58.33%) 75.00–79.16% = 18K (acclaimed 75.00%

Gold Purity Testing 911metallurgist

Test needles (Fig. 47) are a number of slim pointed brass fingers, one end having gold points of different fineness expressed in karats (the karat is the jeweler’s standard of measure for gold, and 24 karats is pure gold). The test needles range from a 2 karat point up to a 20 karat point, advancing 2 karats at a time. Six karat gold would be 6 /24 pure, 8 karat gold would be 8/24 pure gold
