Two specimens of rare "rose" muscovite from a recent find in a pegmatite mine in Taos County, New Mexico. Muscovite is familiar in various hues beyond the usual silver: particularly green, yellow, lavender, and even a reddish orange (Canada).

May 14, 2020 · Some occur as pale, yellow-to-greenish flakes up to an inch in size; most, however, appears as a pink, lithium-rich variety called “rose muscovite.” Rose muscovite contains 3.5-4.6 percent lithium oxide (Li2O) and forms aggregates of tiny, pink crystals.

nnison County, Colorado, contains a highly diversified suite of micas: biotite, m. scovite, zinnwaldite, rose muscovite, sericite, and five major varieties of lepidolite. Each of the micas was formed in a unit of characteristic min-eralogy and texture. …

Rose muscovite grains occur as strongly oriented, Rose or pink muscovites have been described mostly occasionally puckered, impersistent bunches of elongate from pegmatites2 and only rarely from mica schists,
