Petrified Wood - Fossiled Plant material with SiO2

Petrified Wood

Mineral Profile:


Petrified wood is a fossilized form of ancient wood, where organic materials have been replaced by minerals, typically agate or quartz.


Highly prized for its aesthetic appeal, petrified wood is often used in lapidary work to create polished specimens, decorative items, and even jewelry.


Varies widely, displaying a spectrum of earthy tones, including reds, browns, yellows, and greens. The intricate patterns formed during the fossilization process add to its visual allure.


Can range from matte to vitreous, depending on the minerals involved in the fossilization, contributing to its unique and captivating appearance.


While petrified wood is relatively common, specimens with exceptional coloration, large size, or well-preserved features are highly sought after by collectors.

Country of Origin:

Found globally, notable sources include the United States (Arizona, Wyoming), Madagascar, Argentina, and Indonesia.


Typically occurs when wood is buried and replaced by minerals during a process known as permineralization. The replacement minerals, often silica, fill the cellular structure of the wood, preserving its original form.


Ranges from 6 to 7 on the Mohs scale, providing petrified wood with durability suitable for various applications.

Chemical Composition:

Mainly composed of silica (SiO2), with other minerals such as iron oxides and manganese contributing to its diverse color palette and patterns.

Crystal System:

Amorphous, lacking a defined crystal structure, as petrified wood is a result of mineral replacement rather than crystalline growth.


Petrified wood has a rich history, with specimens dating back millions of years. It has been used for practical and ornamental purposes by various cultures, often regarded as a symbol of endurance and timelessness.

Health Information:

Generally safe for handling, but as with any lapidary material, precautions should be taken to avoid inhaling dust during cutting and polishing.

Intended Healing:

Associated with the root chakra, petrified wood is believed to promote grounding, stability, and a connection to nature. Its fossilized nature symbolizes strength and resilience. As with any metaphysical beliefs, individual interpretation and discretion are advised.
