Petrified Conifer Sphere
Araucarioxylon arizonicum
Triassic
Chinle Formation
Arizona, USA
5.46 inches (13.86 cm) in diameter

The contrast between a single rough exterior patch and the surrounding glossy polish gives this Petrified Conifer Sphere a striking interplay of texture and form. Soft bands of cream, gray, and warm beige curve around the piece, preserving the subtle growth patterns once held within the original wood. Concentric zoning and fine internal veining emerge through the Silica-rich mineralization, adding depth to the muted, elegant palette. Light moves gently across the surface, emphasizing the sphere's smooth contours and naturally calming coloration. This distinctive example provides a refined and display-ready expression of Petrified Wood in a classic spherical shape.
