从树皮裂口处或树枝折断处流出并凝固的树脂,经过漫长的地质作用后,便可形成琥珀。由于树脂有微香且黏性大,所以常有各种小生物特别是小节肢动物被粘住且包裹在内,并与空气、水和细菌等隔离。琥珀内的生物也成了保存有生物三维结构的特别化石,往往栩栩如生。琥珀通常为金黄色,有油脂光泽,密度比水略大,易于雕刻成工艺品和饰品,故为人们所喜爱,与珍珠和珊瑚一起被归为有机宝石。
The resin that flows out and solidifies from the bark of a tree bark or at the branch of a tree branches can form amber after a long geological process. Since the resin is slightly fragrant and sticky, it is common for all kinds of small creatures, especially small arthropods, to stick and wrap and to be isolated from air, water and bacteria. Amber’s creatures also become a special fossil preserved biological three-dimensional structure, often lifelike. Amber is usually golden, greasy, slightly denser than water, easy to carve into handicrafts and accessories and is loved by the people and is classified as an organic gemstone with pearl and coral.
