Millesimi

Millesimi is an Italian term that translates to "thousandths" in English. It is commonly used in Italy to denote parts per thousand, a unit of measurement that describes proportions or concentrations, particularly in contexts such as jewelry, finance, and manufacturing. The term originates from the Latin "millesimus," meaning "one thousandth."

In jewelry, millesimi are used to specify the purity of gold, especially for 24-karat gold alloys. For example, an item marked with "millesimi 750" indicates that it contains 75% pure gold, equivalent to 18-karat gold. This system allows consumers to understand the gold content without relying solely on karat markings.

In finance and investment, millesimi are utilized to indicate interest rates, commissions, or other financial proportions expressed per thousand units. For example, a transaction fee might be described as 5 millesimi, meaning five parts per thousand of the transaction amount.

The concept of millesimi complements other measurement units like karat and carat by providing a precise way to express small proportions. Its usage is particularly prevalent in Italy and regions with Italian influence, where it forms part of standard descriptive practices in jewelry manufacturing, trade, and financial transactions.

Overall, millesimi serve as an important unit of measurement for conveying fractional parts in various industries, facilitating transparency and standardization in reporting and quality assessment.
