A very rare and attractive combination of chalcedony and copper (which, when polished, has a beautiful fiery shine, which is almost impossible to photograph), chalcedony also contains other copper minerals (those are the green parts). It comes from Indonesia, specifically from the Moluccas Islands, precisely from the island of Bacan. Cut here.

Copper is a significant energy conductor, both literally and figuratively, and this stone is extremely interesting and powerful. Especially because of how it was formed, where the Earth's plates are moving under each other and there is high volcanic activity - and copper usually comes with it. The stone is literally charged with energy, which is, however, dispersed like slowly released vitamins. It is a very interesting meditation stone.
