585是俄罗斯国家标准规定的金
它包含多达59％的纯金，其余部分-银，钯，镍，铜，锌等。相当坚实和稳固的，良好的形态，在空气中稳定，合金的585样本的主要原料用于制造珠宝首饰，纪念品和物品。

如果还需要其他含量的金，我还可以告诉你。共有如下型号：
375
500
585
750
958
999

纯金是指--》化学符号 Au 金
而且铜的含量超过15%的话，合金就会呈现亮红色。

俄罗斯紫金的纯度是58.5%，即18K金，加的什么合金不知道，但硬度非常高，我曾见过毛子用戒指当起子起啤酒！

其他物质是铜。。含铜量高。造成的黄金发红。。而且冶炼技术也不太和中国一样。。

Rose gold is a gold and copper alloy widely used for specialized jewelry due to its reddish color. It is also known as pink gold and red gold. As it was popular in Russia at the beginning of the nineteenth century, it is also known as Russian gold, although this term has become somewhat rare.

Although the names are often used interchangeably, the difference between red, rose, and pink gold is the copper content–the higher the copper content, the stronger the red coloration, as pure gold is yellow and pure copper is reddish. A common alloy for rose gold is 75% gold and 25% copper by mass (18 carat). Since rose gold is an alloy, there is therefore no such thing as "pure rose gold".
