Many people associate the metal gold with the color gold.
很多人认为金子应该是金色。
But, some gold jewelry is not golden at all: it's white.
但一些黄金首饰的颜色并不是金色，而是白色。
Gold is one of the heaviest and softest metals. Pure gold, called 24-carat gold, is so soft that it can be easily dented.
黄金是最重也是最软的金属之一。纯金，即24k金的质地非常软，很容易产生凹陷。
In the movies, old-time prospectors bite on yellow nuggets to see if they're real gold because 24-carat gold will show a bite mark.
在电影中，以前的勘探者通常会咬一下黄金来试验是否为真金，因为24k黄金会出现咬痕。
In the real world, jewelers don't want to use metal that can be dented so easily. So, most jewelry is actually an alloy of gold with harder metals.
然而现实世界中，珠宝商不希望使用那种易产生凹陷的金属。因此，大多数珠宝其实是黄金与其他硬金属铸成的合金。
Since pure gold is called 24-carat gold, an alloy of half gold and half other metals is called 12 carat gold, because, well, 12 is half of 24.
由于纯金被称为24k金，那么由黄金和其他金属各半铸成的合金被称作12k金，因为12是24的一半。
