Banded Agate Skull $69.99

This skull is carved from banded agate, a variety of chalcedony characterized by its layered bands of color. The alternating light and dark layers form as silica is deposited in rhythmic patterns within cavities of volcanic rock, creating unique striping in every piece.

Details:

• Material: Banded agate (a variety of chalcedony, SiO₂)
• Size: Approximately 2 × 3 inches
• Appearance: Polished skull with visible parallel or curved bands in tones ranging from white and gray to deeper browns or blacks
• Formation: Forms when silica-rich fluids fill cavities in volcanic rock, leaving layered deposits over time
• Physical Properties: Mohs hardness 6.5–7; vitreous luster; fine-grained microcrystalline quartz structure
• Educational Value: Demonstrates chalcedony formation, banding caused by rhythmic mineral deposition, and the durability of quartz-based minerals

This banded agate skull highlights both natural geological processes and skilled craftsmanship, making it a visually striking and educational specimen.
