Physical properties
Hardness: 7 Mohs scale; Color: Creamy white to pale beige; Luster: Vitreous to waxy; Crystal Structure: Trigonal/Hexagonal; Cleavage: None/Conchoidal fracture; Specific Gravity: 2.65.
Formation & geological history
Formed primarily in igneous rocks such as granite or through hydrothermal veins and metamorphic processes. This specimen has been mechanically shaped and drilled for use as a jewelry component.
Uses & applications
Used extensively in jewelry making, beadwork, and decorative arts. In a raw form, quartz is used in glassmaking and electronics.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust. Massive white quartz is often called 'Milk Quartz' when it contains many tiny fluid inclusions.
Field identification & locations
Identify by its hardness (will scratch glass) and lack of cleavage. Look for a waxy surface when polished. Commonly found worldwide in mountain ranges and riverbeds.
