Physical properties

Formation & geological history

Formed through the metamorphism of ultramafic rocks (serpentinization) where hydrothermal fluids introduce iron sulfides and oxides into the magnesium-rich silicate matrix.

Uses & applications

Used primarily for metaphysical purposes, lapidary arts, decorative carvings, and as a collector's specimen.

Geological facts

This specific combination is most famously sourced from Apache Junction in Arizona, USA. It is often called 'Apache Gold' though it contains no actual gold.

Field identification & locations

Identify by its heavy weight (due to magnetite/pyrite content), magnetic properties (will often attract a magnet), and a greenish-black streak. Commonly found in areas with serpentine belts.
