.72" Petrified Wood (Sycamore) Cabochon Pair
This is a beautiful pair of .72" tall petrified sycamore (Platanus sp.) cabochons. This highly detailed petrified wood was collected from the Squaw Creek forest near Kittitas, Washington and has been polished to a glossy finish. These cabochons would be perfect for jewelry making, primarily for earrings as they are a matched pair.
Petrified wood is the name given to wood that has been turned into stone (fossilized) through the process of permineralization. All of the organic matter becomes replaced by minerals, while much of the original structure such as tree rings in retained. For this to happen the wood needs to be buried in an environment both low in oxygen (preventing decomposition) and with flowing, mineral-laden water. The coloration is due to the various minerals that are present during fossilization. For example red colors are due to iron compounds, greens due to copper, etc.
