Petrified Wood Bookends |
BK502c
This is a very beautiful set of Petrified Wood bookends from Arizona.
This set shows the growth lines in the wood and has the beautiful rainbow
colors that sometimes occurs in this Arizona petrified wood. They have
a great polish. This set is polished on one side with a black felt in
the middle and bottom. The set measures 7 1/2" x 5 1/4" x 2
1/8".
Petrified Wood is a type of a fossil as it consists of fossil wood where all the organic materials have been replaced with minerals while retaining the original structure of the wood. These minerals are most often Silicates such as Quartz. Other minerals, Manganese, Iron and Copper, in the water or mud during the petrification process give Petrified Wood a variety of color ranges: black - Carbon; green/blue - Copper; red/brown/yellow - Iron. Petrified Wood can preserve the original structure of the wood in all its detail all the way down to the microscopic level. Structures such as tree rings and the various tissues are often observed features. Although Petrified Wood can be found worldwide, it is rather rare in larger quantities and at times can be difficult to obtain by the average collector. The set weighs 5 lbs. 12 oz. $85.00 |
