*Fineness means parts of gold per 1,000 parts of metal. Figures are common reference grades, not a guarantee of permitted hallmarks in every country. In India, BIS also recognizes 24KS995 for jewellery; 999 typically describes fine gold. 14K is commonly marked 585 rather than the exact mathematical 583.3.
