One of the most spectacular natural wonders that has captured the human imagination for centuries is petrified wood. Formed over many millions of years when trees are covered by sedimentary rocks, organic material is gradually replaced with minerals like silica, calcite, or pyrite. The tree structure, therefore, remains preserved and represents a beauty in stone.
How is this natural wonder formed?
Petroformed wood is normally a result of volcanic regions or floodplains. The final resting place of a tree, when covered with silt, ensures isolation from oxygen, therefore decompaction. The water, with minerals dissolved in it, passes through the pores of the tree; then, when it evaporates, minerals crystallize in the vacuum, gradually replacing the organic material. Thus, a stone is formed with the original structure of the tree preserved in it: rings, bark, and even separate branches.
Type of Petrified Wood
Petrified wood can come in a wide range of color and texture depending on the minerals employed in its formation. Some of the types include:
Agatized wood
In this type, silica replaces organic material in the process, forming a stone that is translucent or even opaque, with a bright spectrum of colors, ranging from red, purple, to green.
Calcitized wood
This will be the kind wherein calcite replaces the organic material; the stone here will be whitish or creamy, and the texture may appear crystalline.
Pyritized wood
Here, the pyrite replaces the organic material and the stone becomes metallic-looking; colors vary from silvery to golden.
Petrified Wood: A Collector's Value
One of the most preferred collector's items is the petrified wood, mainly because this is considered to have extreme value due to its beauty and geological significance that are unique. There is a big difference in the value of this petrified wood for the following reasons:
-
Size: More valuable due to the large specimen size.
-
Color: The brighter and rarer, the higher in price.
-
Texture: To include intricate patterns and textures add value.
-
Origin: The petrified wood from certain locations such as Arizona or Indonesia is sought.
-
Preservation: The more preserved and with good detail on the original tree, the higher in value.
Cost and Price of Petrified Wood
The petrified wood cost can range from dollars for a small, ordinary piece to thousands or even millions of dollars for a rare, high-quality one. In addition to size, color, and texture, the origin and the requirements of the market affect the petrified wood prices.
Where to Buy Petrified Wood
There are several avenues from where the acquisition of petrified wood can be acquired, such as:
Gem and mineral shows
These gatherings usually contain a wide collection of pieces of petrified wood.
Online retailers
Thousands of online stores specialize in selling petrified wood, as well as numerous other types of gemstones.
Local rock shops
Individual rock shops may carry petrified wood, depending on whether they are located in an area known to produce or process that type of geological product.
Conclusion
Petrified wood is a rather hardy material but ought to be dealt with cautiously so as to avoid breakage. Avoid dropping it under extreme temperatures and nasty chemicals. Clean by dusting with a soft cloth.
Actually, that's really a wonderful and natural wonder that can tell the ancient history of Earth. Being of special beauty and geologic importance, it has gained immense popularity among collectors and enthusiasts. Whether one is interested in its scientific value or simply in how it looks, petrified wood is certainly fascinating and timeless treasure.
