Physical properties

Hardness: 7 (Mohs scale); Color: Pale yellow to honey gold; Luster: Vitreous/Glassy; Crystal structure: Trigonal; Cleavage: None/Conchoidal fracture; Specific gravity: 2.65

Formation & geological history

Formed in igneous and metamorphic rocks, particularly in pegmatites or hydrothermal veins. The yellow color is typically caused by trace amounts of iron or natural radiation during the growth process.

Uses & applications

Commonly used in jewelry as a gemstone, decorative carvings, and in metaphysical collections.

Geological facts

Natural yellow quartz is often confused with heat-treated amethyst. While true citrine is rare in nature, yellow quartz (often called ferruginous quartz) is common and gets its color from iron oxide staining or inclusions.

Field identification & locations

Identify in the field by its hardness (will scratch glass), conchoidal (shell-like) fracture, and lack of cleavage. Often found in riverbeds or near quartz veins. Collectors look for clarity and depth of color.
