Precious Metal Stamping
Millesimal fineness is a system of denoting the purity of platinum, gold and silver alloys by parts per thousand of pure metal by mass in the alloy. For example, an alloy containing 75% gold is denoted as “750”. Many European countries use decimal hallmark stamps (i.e. ‘585’, ‘750’, etc.) rather than ’14K’, ’18K’, etc., which is used in the United Kingdom and United States. It is an extension of the older carat (karat in North American spelling) system of denoting the purity of gold by fractions of 24, such as “18 carat” for an alloy with 75% (18 parts per 24) pure gold by mass. The millesimal fineness is usually rounded to a three figure number, particularly where used as a hallmark, and the fineness may vary slightly from the traditional versions of purity.
