Peridot from Tanzania comes from regions associated with the Gogo tribe, a Bantu ethnic group in central Tanzania. The area is known for producing peridot with a strong apple green color 

Peridot is a variety of olivine, formed deep in the Earth's mantle and brought to the surface by volcanic activity. Tanzanian peridot often contains minor iron inclusions, which can influence its color 

The Gogo people have historically been pastoralists, but their land is rich in gemstone deposits, including peridot, garnet, and sapphire
