[Item 12564651] Ethiopian Paraiba Tourmaline 0.350ct Loose Stone

Paraiba tourmaline is captivating for its vibrant blue to green hues. It is characterized by its unique coloration, which is produced by the presence of copper. Discovered in Paraíba State, Brazil, in the 1980s, its production has since been confirmed in places such as Africa. In recent years, copper-bearing tourmaline from Ethiopia has also been mined, drawing significant attention. Currently in Japan, copper-bearing blue to green tourmaline is referred to as "Paraiba tourmaline," regardless of its origin. CuO: 3.059%, MnO: 0.512% (Another stone is currently being submitted to CGL; available after 16:00 on 10/23)
