🌳 Petrified Wood Jasper Sphere – Fossilized Agatized Wood | Madagascar

This large, hand-polished petrified wood sphere displays the warm, earthy beauty of fossilized wood transformed into stone over millions of years. Bands of red, brown, tan, and cream represent ancient growth layers now replaced by quartz and chalcedony, creating an agate-like appearance with exceptional polish and depth. Formed when mineral-rich groundwater permeated buried wood, this specimen captures the structure of the original tree while preserving it in silica — a geological time capsule frozen in stone. ⸻ 🔬 Scientific Information • Mineral type: Agatized / silicified fossil wood (Petrified Wood Jasper) • Composition: Silicon dioxide (SiO₂ – quartz and chalcedony) • Coloration agents: Iron oxides (reds, browns), manganese (black), carbon (gray) • Hardness: 6.5–7 on the Mohs scale • Luster: Glossy vitreous finish when polished • Geologic age: Typically 150–250 million years (Mesozoic era) • Origin: Madagascar (renowned for richly colored petrified wood) ⸻ 📏 Approximate Dimensions • Diameter: ~4.5” (11.5 cm) • Weight: ~2.2–2.4 lb (1 kg)
