Petrified Wood: Gemstone and Jewelry


Petrified wood is a unique gemstone and jewelry material that has fascinated people for centuries. It is a type of fossilized wood that has been preserved over time through a process called petrification, which involves the replacement of organic material with minerals. This article will explore the history, formation, properties, and uses of petrified wood, with a focus on its use in jewelry.


History of Petrified Wood:  

Petrified wood has been known and admired by humans for thousands of years. Ancient cultures, such as the Greeks and Romans, believed that the gemstone had supernatural powers and could ward off evil spirits. Native American tribes in the western United States also valued petrified wood for its beauty and spiritual significance, using it in their ceremonies and as talismans.


Formation of Petrified Wood:  

Petrified wood is formed when trees or other plants are buried by sediment and fossilized over time. The process of petrification begins when water carrying dissolved minerals, such as silica and calcium carbonate, infiltrate the buried wood. Over time, the minerals replace the organic material, turning it into stone. The resulting petrified wood is typically composed of microscopic quartz crystals that give it a unique texture and luster.


Properties of Petrified Wood:  

Petrified wood is a hard, durable gemstone that is resistant to scratches and abrasions. It has a hardness of 7 on the Mohs scale, which is similar to that of quartz. The gemstone is typically brown to black in color, with a distinctive wood grain pattern that is created by the replacement of the original plant material with mineral deposits. The texture of petrified wood is often described as silky or smooth, making it a popular material for lapidary work.


Uses of Petrified Wood:  

Petrified wood is a popular material for jewelry making due to its unique appearance and durability. The gemstone is commonly used in rings, pendants, earrings, and other types of jewelry. It is also a popular choice for decorative objects, such as bookends and paperweights.

One of the most common types of jewelry made from petrified wood is cabochons. Cabochons are polished stones that are used as the centerpiece of a piece of jewelry. Petrified wood cabochons are typically cut in a variety of shapes, including oval, round, and teardrop, and can feature different patterns and colors.

Another popular form of petrified wood jewelry is petrified wood beads. These beads are made from small pieces of petrified wood that have been drilled and strung together on a necklace or bracelet. Petrified wood beads can come in a range of shapes and sizes, from small round beads to large irregularly shaped chunks.

Petrified wood is also used in combination with other gemstones to create striking jewelry pieces. For example, petrified wood and turquoise are often paired together to create unique and eye-catching jewelry designs.



Petrified wood is a unique gemstone and jewelry material that has a rich history and unique properties. Through the process of petrification, trees and other plants have been transformed into beautiful and durable gemstones that are prized for their distinctive wood grain patterns and silky texture. As a popular material in the world of jewelry-making, petrified wood can be found in a range of styles and designs, from cabochons to beads to elaborate necklaces and other pieces of jewelry. Whether you are a collector, enthusiast, or just looking for a statement piece to add to your jewelry collection, petrified wood is a gemstone that is worth discovering.
