Zonální dvoubarevná slída s lepidolitem (slída s lithiem)

The lepidolite bands shimmer differently than the plain mica layers, which I wasn't expecting from the photos. Mine has a soft purple zone running right through the middle of the silver sheets. It's sitting on my windowsill now and the light catches it beautifully.

The color zoning on this specimen is way more distinct than the listing photos suggested, with the silvery mica layers clearly separating from the lithium-rich purple sections. It's a hefty little piece too, and I've already caught myself turning it under different light just to watch the shimmer sh

The purple lepidolite zones against the silvery mica really pop when I hold it up to a window. I've got it on my desk next to a few other specimens and the color zoning catches my eye every time.
