Ct是什麼意思戒指

"CT" in reference to a ring typically stands for "carat", which is a unit of measurement for the weight of diamonds or other gemstones. A carat is divided into 100 points, so a diamond weighing 0.5 carats is the same as a diamond weighing 50 points. The carat weight of a stone is one of the 4 Cs used to describe the quality of a diamond, the others being cut, clarity, and color.
