These polychrome jasper specimens are shaped for display or handling. Polychrome jasper is a variety of chalcedony quartz that exhibits multiple colors and patterns due to mineral impurities and sedimentary layering.
Details:
- Mineral Group: Quartz (SiO₂)
- Material: Natural polychrome jasper
- Shape: Smooth, rounded stone designed for handling
- Appearance: Multi-colored patterns, often including shades of red, brown, yellow, and cream
- Formation: Forms in sedimentary or volcanic environments where silica-rich fluids infiltrate rock cavities and crystallize with varying mineral content
- Physical Properties: Mohs hardness 6.5–7; vitreous to dull luster
- Educational Value: Demonstrates quartz formation, mineral impurities, and pattern variation in sedimentary and volcanic contexts
These polychrome jasper pieces highlight the natural beauty and geological diversity of chalcedony quartz.
