More information
Typically sourced from Brazil (Bahia), Elba Island (Italy), Namibia, and
Afghanistan, this is a typical mineral of Phanerozoic lithium-bearing
granitic pegmatites, associated with spodumene, amblygonite, and
tourmaline. Hardness 6–6.5 Mohs, density 2.4 g/cm³, color ranging
from colorless to pinkish or greyish.
An important industrial source of lithium
(ceramics, glass, batteries); gem-quality varieties are sought by
collectors; rarely faceted for jewelry due to its perfect cleavage.
