In which country do most gem-quality tourmalines form?

Brazil is the leading source of gem-quality tourmalines, renowned for its diverse range of colors and the size of the crystals produced. The country's geological features provide ideal conditions for the formation of these gemstones, particularly in regions like Minas Gerais, where significant deposits have been mined.

Brazilian tourmalines come in various colors, including the highly sought-after Paraíba tourmaline, known for its vibrant neon blue-green hues, which stems from copper content. The Brazilian deposits have played a critical role in the global tourmaline market, making Brazil synonymous with high-quality tourmalines.

While other countries like India, Afghanistan, and Pakistan also produce tourmalines, the quantities and the variety of colors and quality found in Brazil far exceed those from the other locations. This dominance makes Brazil the primary source for collectors and gem enthusiasts seeking gem-quality tourmalines.
