Mined from: Indonesia
Geological Age: 66mya
Description: In the late Tertiary period, blankets of rainforest surrounding volcanos were plentiful. After volcanic eruption, these trees were buried with ash and lava eliminating any microbes that would rot the wood.
The wood was then replaced with silica-rich minerals such as quartz, jasper, calcite, and chalcedony. The colours found in the wood come from an assortment of trace minerals. Maganese creates blue and black colours while traces of iron give the brown and orange colours.
