18k
eight·teen kar·at | ˈāt-ˈtēn ker-ət
adjective
A gold alloy that includes 75% pure gold and 25% alloy
18k alludes to the amount of pure gold in any given piece. Gold is an extremely soft metal that must often be mixed with an alloy to make it more durable. In numerical terms, 18k gold is 75% gold and 25% alloy. The number 18 refers to parts of 24, or karats. 18k gold is the alloy with the highest amount of gold content sold in most rings, and its color is closer to that of pure gold. Due to the metal’s higher value and slightly lower durability, 18k gold is used primarily in the high-end jewelry industry. In addition, it is reasonably pure but is not overly soft. Karat standards may possibly vary from country to country. For instance, in some areas of Europe, the minimum standard is 1BK, while in others, the minimum is 9K.
18k 暗指任何一件作品中純金的數量。 黃金是一種極其柔軟的金屬，必須經常與合金混合以使其更耐用。 在數字上，18k 金是 75% 的金和 25% 的合金。 數字 18 指的是 24 或克拉的一部分。 18k金是大多數戒指中含金量最高的合金，其顏色更接近純金。 由於金屬的價值較高且耐用性略低，18k 金主要用於高端珠寶行業。 此外，它相當純淨，但並不過分柔軟。 克拉標準可能因國家/地區而異。 例如，在歐洲某些地區，最低標準是 1BK，而在其他地區，最低標準是 9K。
