Which location is known as the most important source of aquamarine?

The most important source of aquamarine is indeed Brazil. Brazil has long been recognized for producing some of the highest quality aquamarine gemstones, characterized by their beautiful blue to greenish-blue hues and clarity. The country’s mineral-rich geology, particularly in regions like Minas Gerais and Bahia, contributes significantly to the large deposits and stunning qualities of aquamarine found there.

While each of the other locations listed may have historical significance in the production of aquamarine, Brazil remains preeminent due to its vast quantities and the exceptional quality of the stones mined. China, for example, does produce aquamarine, but its output and the quality do not rival that of Brazil. Similarly, although Afghanistan and India have sources of aquamarine, they are less prominent in the global market compared to Brazil.
