What does the stamp 750 mean on jewelry? “750” stamped jewelry indicates that it contains 18 karat gold. When it comes to precious metals, purity and quality are of utmost importance, with this stamp representing the purity of quality in jewellery made of 18k. To fully comprehend what “750” signifies about gold purity. To gain further understanding about this phenomenon it’s necessary to explore what karats represent as well as how the numbering system operates when applied to gold purity.
Understanding Karats and Gold Purity Grade
Gold is an extremely valuable precious metal that is commonly mixed with other metals to increase its durability for use in jewellery. Pure 24k gold means all 24 parts contain 24K of metal (or 100% gold). However, 100% pure gold can easily be scratched or bent over time, making it impractical for daily wear; therefore, gold alloys such as copper, silver, nickel and zinc are often mixed into their composition to increase strength and durability.
“Karat” (often abbreviated to “kt” or “K”) refers to the proportion of gold found in any 24-part alloy that consists solely of pure gold. Therefore, 18 karat gold, indicated by its hallmark number “750”, signifies 18 out of 24 parts comprise pure gold; that equates to 75% pure gold versus 25% other metals – thus its designation with “750”.
