Joetsu Science Museum Director Nagai
The stones in jewelry stores and watch stores are polished. Here, we display unpolished gemstones. Some of them glow when exposed to ultraviolet light, and others appear to change color when viewed from different angles. I hope you enjoy them.”
The exhibition is held to let people know how minerals are formed in nature.
This is an amethyst gemstone, a geode. It is thought to be crystallized when groundwater, which has dissolved mineral components, enters the rock, which has hardened as a result of magma cooling.
