Sanukite

Sanukite

Also known as Sanuki rock or Kankan stone, it is a very dense copper pyroxene andesite, and is a rare stone that makes a metallic sound when hung from a string and struck.
This beautiful sound reverberated throughout the opening ceremony of the 1964 Tokyo Olympics.
It is one of Japan's 100 best geological sites, and in 2016 it was selected as Kagawa Prefecture's "Prefectural Stone" by the Geological Society of Japan.
Depending on the place of origin, Sanukite comes in male and female forms, and their properties differ.
They also have unusual shapes such as those eaten by insects, rotten wood, pine cones, and dried bonito flakes.
