Physical properties

Hardness: 7 (Mohs); Color: Clear to milky white with green internal phantoms or inclusions; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (trigonal); Cleavage: None; Specific Gravity: 2.65

Formation & geological history

Formed in hydrothermal veins or pegmatites. The green chlorite was deposited on the surface of the quartz crystal during a pause in its growth; subsequent growth then enveloped the chlorite, creating a permanent 'phantom' outline of the crystal's previous stage.

Uses & applications

Predominantly used as a collector specimen and in metaphysical jewelry. Its unique internal geometry makes it highly desirable for display.

Geological facts

Phantom crystals act as a geological timeline, showing a 'frozen' moment in history when mineral-rich fluids changed composition. These specimens are often called 'green phantoms' and are highly popular in crystal healing circles.

Field identification & locations

Identify in the field by looking for the 6-sided prism shape typical of quartz with distinct green mossy or triangular zones inside. Commonly found in regions with significant tectonic activity like the Alps in Switzerland, Brazil, and the Himalayan mountains.
