About Cacoxenite
A hydrated iron aluminum phosphate, often found as yellowish to brownish radiating acicular inclusions in quartz or amethyst. It's considered a high-vibration 'stone of ascension,' enhancing spiritual awareness and intuition. (Note: 'Cacoxenite in Amethyst' is often Goethite or other iron minerals).
Primary Hues
Yellow, Golden-Yellow, Brownish-Yellow, Reddish-Brown, forms acicular or fibrous inclusions
