Physical properties
Hardness: 7 (Mohs scale), Color: Colorless to white/grey with internal visible ghost-like layers, Luster: Vitreous, Crystal Structure: Hexagonal, Specific Gravity: 2.65
Formation & geological history
Formed in hydrothermal veins when crystal growth was interrupted by mineral deposition (like chlorite or clay) and then resumed, creating internal outlines of previous growth stages.
Uses & applications
Primarily used as a collector specimen, for metaphysical purposes, and occasionally in ornamental jewelry pieces.
Geological facts
The internal outlines, or 'phantoms,' act as a geological record of the crystal's growth history over thousands of years.
Field identification & locations
Identify by looking for distinct shadow-like or line inclusions that mimic the shape of the outer crystal. Frequently found in Brazil, Madagascar, and Arkansas, USA.
