Clear Quartz, Faden Quartz, From India, 13690g

Faden quartz forms in cracks in the host rock that widen slowly. If the crystal is attached to both walls of the opening, the rupturing and healing will repeat, leaving a scar of liquid and gas inclusions in the crystal—resembling a white thread, known as the faden.
This specimen naturally forms in the shape of a spaceship, making it exceptionally special and rare.
