A very rare form of fossil wood that, in addition to the usual calcification, also contains chrysocolla, hence the abbreviated name Colla wood / or Chrysocolla wood. It comes from the island of Sumatra. You might be interested in how such beautiful greenish fossils came to be: the island of Sumatra is of volcanic origin, and specifically in these volcanoes, a lot of copper was also found. During an ancient explosion, the prehistoric forest was buried under a volcanic mantle, and siliceous and copper minerals (such as chrysocol), over time saturated and preserved future beautifully colored fossils. There are not many green woods of this type in the world. Our (no less beautiful) Czech "wood" is mostly earthy, even black, because it has been saturated with siliceous solutions containing iron minerals).. in layman's terms. In short, we love all fossils, and we are excited when we get our hands on something like this....

Grinded by us. Can be drilled.

Petrified wood is a strong fossil, connected to the earth and physical being, just as many things can be made from wood, so a person can unexpectedly discover who they really are, what is hidden inside. But this wood has a playful approach to the process, and works through physical and emotional stimuli. So, if you only think about something, it won't help you a bit, but if you start doing something, it will be a great guide.
