Collection: Petrified Wood Collection

Shop natural petrified wood specimens and slabs for collecting, display, and lapidary work. Our petrified wood collection features polished petrified wood slabs with preserved wood grain and growth rings, petrified wood cabochons, raw chunks, and bookends sourced from Arizona, Indonesia, Madagascar, and Ethiopia. Petrified wood forms over millions of years as organic wood tissue is gradually replaced by silica minerals — primarily quartz, chalcedony, and opal — while preserving the original cellular structure, grain patterns, and growth rings in stunning detail. Arizona petrified wood from the Triassic period (220+ million years old) is among the most colorful in the world, with iron and manganese oxides producing vivid reds, oranges, yellows, purples, and blacks. With a Mohs hardness of 7, petrified wood is durable and excellent for cabochons, slabs, and display pieces. Ethically sourced with full origin disclosure.
