Physical properties

Formation & geological history

Formed in hydrothermal veins and pegmatites where silica-rich fluids cool. Green chlorite minerals are trapped inside the quartz as it grows, often during the metamorphic or late-stage igneous process.

Uses & applications

Used primarily as decorative collector specimens, in metaphysical practices, and occasionally faceted into unique jewelry pieces.

Geological facts

These are often called 'Phantom Quartz' if the chlorite forms a layer that mimics the shape of the crystal inside. They are highly sought after by collectors for their 'mossy' or 'forest-like' internal appearance.

Field identification & locations

Identify in the field by looking for standard quartz crystal points that contain visible green moss-like or flakey internal inclusions. Commonly found in alpine-type fissures in Brazil, Switzerland, and Arkansas, USA.
