Crystallized Petrified Wood Slice 4” x 3 1/2”

Petrified wood is made up of almost solid quartz. The colors are produced by impurities in the quartz, such as iron, carbon, and manganese. Over 200 million years ago, the logs washed into an ancient river system and were rapidly buried deep enough by sediment and debris also carried in the water. Oxygen was cut off and decay slowed to a process that would now take centuries. Minerals, including silica dissolved from volcanic ash, absorbed into the porous wood over thousands of years crystallized within the cellular structure, replacing organic matter over time.

Material & Craftsmanship

Ethically sourced from Arizona's premium petrified wood deposits and expertly handcrafted in the USA. At 11" × 7.25" × 2", these bookends are exceptionally large—pieces of this size and quality are increasingly rare in today's market.

Petrified wood forms when ancient trees are rapidly buried by sediment or volcanic ash in river systems, cutting off oxygen and halting decay. Over millions of years, minerals including silica dissolved from volcanic ash absorb into the porous wood and crystallize within the cellular structure, completely replacing organic matter with stone while preserving the tree's original form.

The Science of Color

The rich hues in petrified wood come from trace minerals present during fossilization:

• Red & Rust: Iron oxide (hematite)
• Yellow, Brown & Orange: Goethite and hydrated iron oxide
• White & Cream: Pure silica
• Black: Organic carbon or pyrite
• Blue: Chalcedony, chrysocolla, cobalt
• Green: Copper and cobalt
• Pink: Manganese

Dimensions: 11" × 7.25" × 2"
Weight: 31 lbs (pair)

Age: Over 200 million years
