Description
An elongated, terminated crystal of green quartz, exhibiting a range of green hues from lighter olive at the top to darker green towards the base, likely due to varying concentrations of chlorite inclusions.
Geological Context
Quartz forms in a wide variety of igneous, metamorphic, and sedimentary rocks. The presence of chlorite inclusions suggests formation in a low-grade metamorphic or hydrothermal environment, where chlorite minerals are stable.
