<a href="http://www.chowsangsang.com">黄金</a>是一种尊贵的金属，能抵抗侵蚀，光泽恒久。<a href="http://www.chowsangsang.com">黄金</a>的质地较软，可以炼成各种形状。在香港，黄金的销售以两为单位，每两相等于37.429克。制造<a href="http://www.chowsangsang.com">首饰珠宝</a>，可用<a href="http://www.chowsangsang.com">纯金</a>（即24K或999.9黄金）或不同纯金度的合金（又称「K金」）。黄金混入铜、银或钯便成合金，最普遍的是<a href="http://www.chowsangsang.com">18K金</a>（含75%纯金）及14K金（含58.5%纯金）。由于合金较黄金坚硬，所以较适合镶嵌钻石或宝石的珠宝饰件。 随着混合金属的比例不同，合金的颜色及硬度也相应有分别。例如含铜量较高的合金会令颜色偏红或玫瑰红；而含银量较高的合金则会呈白色。「<a href="http://www.chowsangsang.com">K白金</a>」是银白色的K金，不含铜，只含有银及镍或钯。
