According to national regulations, regular jewelers should print their own logos on precious metal jewelry, including trademarks, precious metal classification, purity and so on. As the most expensive gem, diamond is the quality of standard diamond, that is, the number of carats, which is specially stipulated by the state to be printed on the mark. Provided that the independent mass of the diamond as the main stone exceeds 0. 10 carat. That is to say, only when the weight of a single diamond exceeds 0. 10 carat will there be printed marks. The mark is represented by D0 10ct or D0 10, where "d" refers to diamond, the first letter of the English word "diamond", and 0 10 is the number of carats. For convenience, decimal marks are generally not used. "ct" is the abbreviation of carat in English, that is, "carat". Sometimes ct can be unmarked. Therefore, the expression of diamond mark on precious metal jewelry is: D+ carat number +ct (can be omitted).
