Amber is widely distributed in the world, and the Baltic amber is famous, and the quality of natural amber produced on the southern shore of the Baltic Sea is considered to be the best. In addition, the world famous Amber City Gdansk is also here. Due to the special geological, historical and climatic conditions, the Baltic Sea produces a wide variety of amber varieties, which are transparent, translucent and opaque; the colors are also very large, yellow, red, brown, white, blue, green and so on. There are two main types of output in the Baltic amber: (1) Haiper: This natural amber is produced in the sea and can float on the water. The locals call it “sea stoneâ€. The amber-bearing formation in the sea or near the sea is washed away by sea water, and amber can also be washed out, while the beach is still floating a lot of artificially mined amber raw materials. (2) Hangper: This type of amber is harvested from mines near the Baltic coast and is similar in quality to the amber raw material produced in the Baltic Sea. According to the investigation, the amber ore-bearing layer on the Baltic coast is an undiagenetic peat layer with a thickness of 4-5 meters and a thickness of more than ten meters. Amber is layered and lumpy, and the upper part of the ore-bearing layer is looser. Local mining is generally open or pit mining. Excavate along the amber-bearing deposit. Due to the convenience of mining, a worker can pick up to hundreds of kilograms of raw materials per day during the early years.
