Physical properties

Mohs hardness of 7, vitreous to waxy luster, yellow to honey-orange color, trigonal crystal system, no cleavage, conchoidal fracture, specific gravity 2.65

Formation & geological history

Formed in igneous or metamorphic rocks through hydrothermal processes or silica-rich fluid precipitation in veins and cavities. This specimen appears water-worn or tumbled.

Uses & applications

Used in jewelry, decorative ornaments, lapidary arts, and by mineral collectors. It is also a popular stone in metaphysical circles.

Geological facts

Natural yellow quartz is rare; much of the citrine on the market is actually heat-treated amethyst. When it has a more opaque, waxy appearance like this specimen, it is often referred to as yellow jasper.

Field identification & locations

Identified by its hardness (can scratch glass), lack of cleavage, and yellow hue. Often found in riverbeds, glacial tills, or near quartz veins.
