Fuchsite is actually a rare bright to dark green variety of the common mineral muscovite. In these rare quartz crystals from Pakistan, it takes the form of bright, light green inclusions inside a tabular crystal of quartz. Unusual material from, so far as I know, a single pocket. Over the years I have seen perhaps less than 10 specimens from this pocket found in 1993, which produced strange quartzes of an unearthly green color. They initially were labeled everything from Chrysoprase crystals to Quartz included by dye. It turns out, so far as I know now, that the color is due to dispersed microscopic inclusions of fuchsite, a green mica species. This particular crystal is a superb thumbnail and a floater, complete all around.
