Polished Arizona Rainbow Petrified Wood
Arizona Rainbow Petrified Wood polished slab. Cut and polished to a mirror finish in my lapidary workshop. The colors are purple, tan, cream yellow and some red. Petrified or fossilized wood is generally the result of great floods, The wood is buried deep in the muck where it can no longer get any oxygen and will not decompose. This is a process that takes place over millions of years. Arizona rainbow is mostly quartz. The impurities in the quartz give it the colors. This piece has a few fractures. It is still a very nice specimen.. Width 5 3/4″. Height 4 5/8″. Thickness 1/2″.
