Brazil is the world’s leading source of gem-quality aquamarine for over 100 years. It is found there in both pegmatites and alluvial deposits. Afghanistan, Kenya, Madagascar, Malawi, Mozambique, Nigeria, Pakistan, Russia, Tanzania, and Zambia are all sources of aquamarine. India and Sri Lanka have long histories of aquamarine production from alluvial deposits.

Aquamarine has been found at many locations in the United States. To date, almost all of the production has been from small-scale mining, often where multiple minerals are being produced.
