II. The Scientific Reading

What the lattice actually does.

Nellite is a trade name for a pyrophyllite-quartz composite from China with a subtle silky sheen. It forms in low-grade metamorphosed silica-rich rocks where pyrophyllite develops alongside microcrystalline quartz, giving the stone its characteristic mottled cream-pink appearance.
