The Beauty of Petrified Wood

Petrified Wood is undoubtedly the most spectacularly beautiful of all varieties of fossils. It is a rare find and only a small proportion of the petrified wood can be cut and polished into pieces which can become prized specimens for collectors who appreciate its beauty. Collectors prize specimens for many different reasons including the quality of the material, the location of the forests from where specimens were sourced and the rarity of the fossilized wood.

Petrified Wood Slabs

 

Petrified wood is formed when a tree completely transforms to stone as all the organic material gets replaced by minerals. This process is called peri-mineralization. The petrifaction takes place under the ground when the wood gets buried under sediment and this process can take millions of years. The result is a very strong material with the structure of wood. The color is determined by the type of mineral. Depending on the predominant minerals that seeped with the cell structure of the wood, petrified wood has different colors ranging from subtle browns to vibrant blue-greens. 

Black Petrified Wood

The black color in petrified wood is derived from the presence of pyrite or organic carbon in the soil mineral. Pyrite sparks when it is struck and is called ‘fire mineral’. A completely charcoal black petrified wood piece is rare and it requires a true connoisseur's eyes to appreciate the textural markings in the subtle variations of charcoal black. 

 

White Petrified Wood

The white color is petrified wood is due to the presence of Silicon Dioxide, commonly known as free Silica, occuring in the form of quartz.

Blue Petrified Wood

Blue and purple hues in petrified wood are created by the presence of manganese dioxide. 

 

Tan Petrified Wood

This tan color in petrified wood  is the most common color of petrified wood. In this case, the structure of the wood is preserved better and produces an appearance or actual wood. This is due to the presence of silica dioxide.

Green Petrified Wood

The green color in petrified wood is obtained from iron in the soil.

 

Red Petrified Wood

The red and pink color in petrified wood is produced by the presence of a form of oxidized iron called hematite. The color can be normal or more vibrant depending on the amount of hematite present in the soil.

 

Orange Petrified Wood

Brown,yellow, and orange colors in petrified wood are created when goethite is present in low temperature conditions. The exact shade it imparts is a brown ochre.
