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

The most important source of aquamarine is Brazil. Brazil has gained worldwide recognition for its high-quality aquamarine deposits, particularly from regions such as Minas Gerais. The stones mined from Brazil are often prized for their vibrant blue hues and clarity, making them highly sought after in the gemstone market.

In contrast, while China, Afghanistan, and India do produce aquamarine, their contributions to the overall availability and quality of this gemstone are not as significant as Brazil's. Other countries may have notable deposits, but Brazil's rich history and depth of production ensure it remains the leading source of aquamarine. This understanding is crucial for anyone working with or evaluating colored stones, as it impacts both sourcing and valuation.
