History

Chromium works its mineral-magic to make fuchsite appealingly green. The presence of chromium in gemstones (think ruby and emerald) is most often indicative of exciting color. Fuchsite is an excellent example of the effects of chromium. This sparkling green mica is a variety of muscovite. Micas are often added to makeup - they are the additive most responsible for the "youthful glow" that is so pleasing in foundations and eye shadows.
