Paraiba tourmaline is prized for its captivating hues ranging from vivid blue to green. It is characterized by a unique coloration born from its copper content. First discovered in the Brazilian state of Paraiba in the 1980s, its production has since been confirmed in Africa and elsewhere. In recent years, copper-bearing tourmaline from Ethiopia has also gained attention. In Japan, blue-to-green tourmaline containing copper is referred to as "Paraiba tourmaline," regardless of its origin.

This is an Ethiopian Paraiba tourmaline that we have just sourced in Hong Kong. For this piece, rather than focusing solely on transparency, we selected a stone that allows you to enjoy the vivid color and neon glow characteristic of Paraiba tourmaline. It contains 2.29% CuO (copper oxide) and 0.62% MnO (manganese oxide). This is a loose stone that you can enjoy not only for its visual beauty but also for the components that give it its color. It comes with a GIA identification report and a compositional analysis document obtained by our company.
