Clear Quartz Sphere
Quartz (Silicon Dioxide, SiO2)
Rock Type: mineral

Physical Properties
Hardness: 7 on Mohs scale; Color: Colorless/Transparent; Luster: Vitreous (glassy); Crystal Structure: Trigonal/Hexagonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65.
Formation & Geological History
Formed through the cooling of silica-rich magma or from hydrothermal veins. It can be found in igneous, metamorphic, and sedimentary environments globally, occurring throughout all geological ages.
Uses & Applications
Used in electronics for its piezoelectric properties, glassmaking, abrasives, and as a popular gemstone for jewelry, meditation, and decorative crystal spheres.
Geological Facts
Quartz is the second most abundant mineral in Earth's continental crust. Pure clear quartz is often called 'Rock Crystal', derived from the Greek word 'krystallos', meaning ice.
Field Identification & Locations
Identify in the field by its hardness (scratches glass), lack of cleavage, and hexagonal crystal habits. Common in pegmatites and riverbeds. For collectors, clarity and the absence of internal fractures increase the value.
