Physical properties

Formation & geological history

Formed in hydrothermal veins or pegmatites where silica-rich fluids mix with iron oxide (hematite or limonite). The red color can be a surface coating or internal inclusions layered during crystal growth.

Uses & applications

Mostly used for ornamental objects, tumbled stones for collectors, wire-wrapped jewelry, and by metaphysical practitioners for 'grounding' energy.

Geological facts

Also known as Fire Quartz or Harlequin Quartz, it is valued for its unique 'starburst' or 'flaky' red inclusions that look like fire trapped inside the crystal.

Field identification & locations

Identify in the field by its hardness (will scratch glass), lack of cleavage, and the presence of internal red specks or moss-like inclusions rather than a solid opaque red color found in jasper.
