Quartz Crystal

Hardness of 7 on the Mohs scale, transparent to translucent, vitreous luster, hexagonal crystal system, and conchoidal fracture.

Forms in igneous, metamorphic, and sedimentary environments through the cooling of silica-rich fluids over millions of years.

Widely used in electronics for oscillators, glass manufacturing, abrasives, and as a popular gemstone and mineral specimen.

Quartz is the second most abundant mineral in Earth's continental crust and exhibits piezoelectric properties, generating an electric charge under mechanical stress.

Identified by its high hardness, lack of cleavage, and distinct hexagonal crystal habit; commonly found worldwide in pegmatites and hydrothermal veins.
