Physical properties

Hardness: 7 (Mohs); Color: Pale yellow to greenish-yellow; Luster: Vitreous; Crystal structure: Trigonal/Hexagonal; Cleavage: None/Conchoidal fracture; Specific gravity: 2.65

Formation & geological history

Formed in igneous and metamorphic environments, specifically pegmatites and hydrothermal veins. Often created by heating natural amethyst or smoky quartz in the presence of iron to achieve the lemon hue.

Uses & applications

Primarily used for decorative purposes, jewelry (faceted gemstones, beads), and as metaphysical/meditative tools (towers/points).

Geological facts

Unlike natural citrine, lemon quartz often has a distinct greenish-neon undertone. It is almost always the result of artificial irradiation followed by heat treatment to produce this specific saturation.

Field identification & locations

Identify by its hardness (will scratch glass), lack of bubbles (unlike glass imitations), and distinct hexagonal prism shape. Commonly found in Brazil, Madagascar, and Russia.
