Physical properties
Hardness: 7 on Mohs scale; Color: Colorless to transparent; Luster: Vitreous (glassy); Crystal Structure: Hexagonal; Cleavage: None/Conchoidal fracture; Specific Gravity: 2.65
Formation & geological history
Formed in igneous, metamorphic, and sedimentary environments, most commonly crystallized from silica-rich hydrothermal solutions or cooling magma at high temperatures and pressures.
Uses & applications
Used in electronics for high-frequency oscillators (quartz clocks), glass manufacturing, abrasives, jewelry, and as decorative metaphysical specimens.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust. This specific specimen has been artificially cut and polished into an obelisk or tower shape.
Field identification & locations
Identify by its hardness (scratches glass), hexagonal shape (when natural), and lack of cleavage. Commonly found in pegmatites, veins, and alpine clefts worldwide, notably in Brazil and Arkansas, USA.
