Petrified Wood Coasters

Scientific Name:
Dipterocarpus sp.
20 Million Years
Approximately 4" Diameter

Petrified Wood Coasters

The Science

The petrification process occurs when wood becomes buried under sediment, such as volcanic ash (most petrified wood is associated with volcanic activity), and is preserved due to a lack of oxygen, inhibiting aerobic decomposition. Over millions of years, water bearing silica trickles down through the sediment and the silica forms crystals in the cells and hollows of the wood. Eventually the wood is completely mineralized, often preserving minute structural detail. The different minerals in groundwater are what give petrified wood its variety of colors. 

The Story

These Petrified Wood Coasters are made from medium-sized branches that have been thinly sliced. The tops and bottoms have been polished to a shine, but the edges have been left rough so that the petrified bark can be appreciated. We've added cork bumpers to the bottom of each coaster to protect your surfaces. What's old is new again with Evolution's extensive petrified wood collection!

Individual shapes and colors vary but your item will resemble the pictured examples.
