Physical properties

Hardness: 7 (Mohs scale); Color: Pale orange to peachy pink; Luster: Vitreous to waxy (when weathered); Crystal structure: Hexagonal/Trigonal; Cleavage: None (conchoidal fracture); Specific gravity: 2.65.

Formation & geological history

Formed in igneous and metamorphic environments, typically crystallizing from hydrothermal veins. The orange hue is caused by inclusions of iron oxides such as hematite or limonite during formation.

Uses & applications

Used primarily in lapidary arts, for ornamental carvings, pocket stones, and as metaphysical healing crystals. Industrial grade quartz is used in glassmaking and electronics.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. When the orange color is very deep and transparent, it is officially classified as Citrine, but opaque or milky specimens are generally called Orange Quartz.

Field identification & locations

Identify in the field by its hardness (it will scratch glass) and lack of cleavage. It is found globally, with major deposits in Brazil and Madagascar. Collectors look for clarity and vibrant saturation.
