Formed when a quartz crystal pauses its growth, another mineral settles on its surface, and growth resumes. The ""mountain"" visible inside is the outline of the crystal at the moment it stopped.
The green is usually chlorite. Where growth interrupted and resumed multiple times, the mountains appear in layers. Within a single crystal, the fault lines of time made visible.
Found in Brazil and Madagascar. No two phantoms share the same shape—each records the exact changes in growing conditions. A tree with no rings, marking time by other means.
