Physical properties
Hardness: 7, Color: typically clear, white, or lightly tinted (in this case, light peach/orange due to iron impurities), Luster: Vitreous, Crystal structure: Hexagonal, Cleavage: None (conchoidal fracture), Specific gravity: 2.65
Formation & geological history
Formed in cavities in volcanic or sedimentary rocks where silica-rich water seeped in and deposited quartz crystals over thousands or millions of years.
Uses & applications
Popular among collectors, used for decorative purposes, sometimes used in jewelry or metaphysical practices.
Geological facts
Geodes are often hollow, allowing crystals to grow inward. The coloration in this specimen suggests the presence of iron oxide (like hematite or goethite) causing the peach/orange hue.
Field identification & locations
Identified by its crystal shape, hardness (scratches glass), and formation inside a nodule/geode. Commonly found globally, particularly in areas with past volcanic activity or specific sedimentary formations.
