Physical properties

Hardness: 7 on the Mohs scale. Color: Pale pink to white/opaque. Luster: Vitreous (glassy) to greasy. Crystal Structure: Trigonal/Hexagonal. Cleavage: None (conchoidal fracture). Specific Gravity: 2.65.

Formation & geological history

Formed through the crystallization of silica-rich magma or from hydrothermal veins. This specimen likely originated in a pegmatite or quartz vein and can range from millions to billions of years in age depending on the host formation.

Uses & applications

Used in the production of glass, ceramics, and electronics (due to piezoelectricity). Pink varieties are popular in jewelry, lapidary arts, and as decorative 'healing' stones in the metaphysical community.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Rose quartz gets its color from trace amounts of titanium, iron, or manganese, and it rarely forms well-defined crystals, usually appearing in massive clusters like this specimen.

Field identification & locations

Identify in the field by its ability to scratch glass (hardness 7), lack of cleavage, and glassy luster. It is commonly found in mountainous regions, riverbeds, and as part of granite outcrops globally.
