Description
This specimen features a large, well-formed pale purple to white quartz crystal with distinct pyramidal terminations. It exhibits reddish-brown color zoning and contains numerous dark green to black acicular epidote inclusions, particularly concentrated near the base and within the crystal.
Geological Context
Quartz, including the amethyst variety, commonly forms in hydrothermal veins and igneous environments. Epidote inclusions suggest formation in a geological setting where both minerals could crystallize, often associated with regional metamorphism or hydrothermal alteration of calcium-rich rocks.
