1910-45 illegal mining in the cave during the Japanese occupation.
1981 amethyst nominated as one of Korea's representative jewels.
1982 Jeil Mining Industry established for active and effective mining.


The area around Eonyang is famous for its amethyst, a violet variety of quartz crystals. In about 50 mines the semi precious mineral was mined for centuries. One of the mines, Jasujeong, a huge system with two different levels, is now open for the public. The passages are quite spacious, about 2 m to 15 m high and used for various purposes.

The site is now called 자수정동굴나라 (jasujeongdong-gulnala, Amethyst Cave Country). It is said to be the largest cave theme park in Korea. There is a mining exhibition, which is for some reason called caving, which is at least consistent as they insist on calling the gem mine a cave. There is a passage with groundwater in the lower level, which is used for boat rides. Another passage is equipped with extremely kitschy oversized replicas of Disney figures, which is actually at the border between weird and fearsome. And finally there is a so-called New Media Center with epilepsy-inducing coloured flickering lights.
