关键字：什么是狗头金
什么是狗头金？狗头金实际上是一种天然的实物黄金，因形状像狗的头部而闻名，因此狗头金是一种未经雕琢的黄金结晶体，下面我们一起了解下狗头金的成分、狗头金的常见形态以及狗头金的收藏意义。
一、狗头金的成分
狗头金是天然形成、黄金纯度不高、颗粒大而形状不规则的类似石头物质的结晶体，成分一般是自然金、石英和其他矿物集合体。其中自然金的质地含有少量其他金属，蕴含白银比例较多，另外也有铜铁铂等。
二、狗头金的形成条件
狗头金的形成条件相当复杂，从研究人员发布的信息可了解到，狗头金是通过微生物在可溶态金中吸附并发酵为天然质金所得，另外也有富含金质的流星陨落这一说法。
三、狗头金的常见形态
狗头金的常见形态主要分为金包石、石包金和金包水，金包石为外层是自然金，内层是石英等矿物质，石包金与金包石形态刚好相反，金包水为外层是自然金，内层是水溶性矿物成分。
四、狗头金的收藏意义
现在世界上的许多地方，不管机构标本处理还是个人收藏，狗头金的估价都是相当之高，因大自然界存在狗头金的地块稀缺，只有极微的偶然机会才能捡到。远古以来人们都把拾取狗头金当作是收获福气的象征，以便贵金属投资增值。
