Nigeria
Nigeria includes ancient basement terrains, younger sedimentary basins, and volcanic provinces. It is widely associated with pegmatite-related gemstones and industrial minerals, alongside common building stones like granite and sandstone.

Geologic snapshot
Major settings
- Precambrian basement complexes with granites and gneisses
- Pegmatite belts hosting gem and industrial minerals
- Sedimentary basins with sandstones and shales
What this means for stones
- Gem materials can occur in pegmatites (tourmaline, beryl)
- Granite and related hard rocks are common building stones
- Sandstones and laterites are important in some regions
Common stones & materials
Nigeria is often referenced for pegmatite-related gemstones (including tourmaline and aquamarine in some localities) and for widespread granites used in construction. Sedimentary rocks also contribute aggregates and building stone.
Care & handling notes
Quartz and beryl gems are generally durable, while some tourmalines can be brittle on edges. For granite surfaces, use pH-neutral cleaners and avoid abrasive pads on polished finishes.
