Polished Natural Petrified Wood Gemstone Spheres Price is for 1 piece Size: 16-18cm Approximate Weight: 5-5.5 kilograms, 6-6.5 kilograms Origin: Indonesia Petrified Wood is a remarkable stone of transformation, created when ancient trees undergo a unique fossilization process over millions of years. This process occurs when wood is buried under sediment and protected from decay by oxygen. Over time, mineral-rich water flows through the sediment, gradually replacing the organic material of the wood with minerals like quartz, chalcedony, and jasper, while retaining the original structure of the tree. The result is a breathtaking fossil that combines the natural patterns of wood with the enduring beauty of stone.
