Moonwood Petrified Wood (UV)

This Moonwood Petrified Wood Rough Stone is an extraordinary, dual-display fossil specimen that bridges the worlds of paleontology and fluorescent mineral collecting, found in the state of Arizona. Millions of years ago, ancient timber was deeply buried by volcanic ash, allowing silica-rich groundwater to permeate the cellular pathways and replace organic wood fibers with dense chalcedony and opalized quartz. What sets this specific rough material apart is its remarkable ultraviolet reactivity. When exposed to a blacklight, the unpolished exterior transforms, fluorescing a brilliant, ghostly neon green due to trace activations of uranyl ions embedded within the silicate matrix during the fossilization process.

In its natural state, this Moonwood Petrified Wood Rough Stone displays a beautiful, rugged texture that perfectly preserves the original botanical anatomy, including distinct growth rings, outer bark ridges, and internal grain structures. Under standard lighting, the stone features an attractive, earthy palette of muted grays, creamy whites, tan bands, and rich charcoal tones. Because this material is kept entirely raw and unrefined, it offers an authentic, tactile look at the prehistoric mineral replacement process, maintaining the jagged, natural edges and textured surfaces that rockhounds appreciate.

Each Moonwood Petrified Wood Rough Stone in our inventory is hand-selected to guarantee strong structural integrity and high fluorescent density. Registering a solid 6.5 to 7 on the Mohs hardness scale, these durable fossil specimens are perfect for educational geology sets, outdoor rock gardens, or dedicated blacklight display cases. Because no two ancient trees petrified under identical environmental conditions, each raw specimen features a completely unique shape, grain direction, and UV glowing pattern, providing a mesmerizing, interactive centerpiece for your private mineral gallery.
