Lithium-bearing pink quartz (likely lepidolite-bearing quartz)

Quartz, SiO₂, with probable lepidolite mica (K(Li,Al)₃(Si,Al)₄O₁₀(F,OH)₂) and minor feldspar

AI-generated identification · may be incorrect

White-to-lavender, massive and sugary/drusy, with vitreous-to-pearly sparkle; quartz hardness is 7, while lepidolite is about 2.5–3. Cleavage is absent in quartz but mica may show basal cleavage; specific gravity is approximately 2.6–2.9.

Physical properties

Formation & geological history

Likely formed in a late-stage granitic pegmatite, where silica-rich fluids crystallized quartz with lithium mica and feldspar. Pegmatites are generally late Precambrian to Phanerozoic, depending on locality.

Uses & applications

Primarily a collector specimen; attractive pieces may be polished or displayed. Quartz is widely used in glass, electronics, and abrasives, while lepidolite is a lithium-bearing mineral but is rarely an economic ore by itself.

Geological facts

The lavender coloration commonly comes from lepidolite or manganese-related impurities rather than purple amethyst. Sparkling surfaces may be fine quartz crystals or mica flakes.

Field identification & locations

Look for glassy quartz, flaky mica with perfect sheet cleavage, and association with feldspar or other pegmatite minerals. Common sources include Brazil, Madagascar, Afghanistan, and U.S. pegmatite districts.
