Physical properties
Hardness: 7 on Mohs scale; Color: Milky white to translucent; Luster: Vitreous to waxy; Crystal structure: Trigonal/Hexagonal; Cleavage: None/Conchoidal fracture; Specific gravity: 2.65.
Formation & geological history
Quartz forms in various geological environments, most commonly by crystallization from magma or hydrothermal pulses. It can also form through sedimentary and metamorphic processes. This specific specimen has been carved and polished into a star shape.
Uses & applications
Used primarily for ornamental purposes, metaphysical and spiritual collection, jewelry charms, or as pocket stones. Industrial quartz is used in glass making and electronics.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust. Stars are a common shape carved in the 'new age' crystal market to represent celestial energy and hope.
Field identification & locations
Identify by its hardness (will scratch glass) and lack of cleavage. This specific item is a manufactured shape, so it is easily identified by its symmetrical 5-point star geometry and polished surface.
