means A naturally occurring variety of quartz that combines amethyst and citrine in a single crystal, showing purple and yellow zones together.
from A portmanteau, blending 'amethyst' and 'citrine' — the two quartz varieties it physically merges. Amethyst comes from Greek 'amethystos,' meaning 'not drunken,' from the old belief the stone warded off intoxication; citrine takes its name from the Latin 'citrus' for its lemon-yellow hue. The fused word itself is fairly modern, tied to the stone's commercial recognition, much of it sourced from a single Bolivian mine.
