    Diamonds Found in kimberlite pipes in Australia, Botswana, Brazil, Congo, South Africa, Russia, and China.
    Rubies and Sapphires Found among alkaline basaltic rock or metamorphic rocks in Sri Lanka, India, Madagascar, Myanmar, and Mozambique.
    Emeralds Mined among sedimentary deposits in Colombia and among igneous rock in Zambia, Brazil, and Mexico.
