Wow! Unique giant natural etched purple and yellow frosty raw fluorite specimen

Rare and giant, naturally etched fluorite specimen from Hardin County Illinois. Dark purple fluorite after golden yellow fluorite. Etched and rough surface--I am guessing that during its creation, the liquid fluorine in the geode cavern ran out of limestone to react with (to create the fluorite crystals) and then started eating away at the crystalline structure, leaving a beautifully rare form of rough, textured fluorite. A new find from Elizabethtown, Illinois. 4"x2"x3"
