[Item 12564645] Ethiopian Paraiba Tourmaline 0.114ct Loose Gemstone

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 the Brazilian state of Paraiba in the 1980s, its production has since been confirmed in other locations, including Africa. In recent years, copper-bearing tourmaline has also been mined in Ethiopia, attracting significant attention. Currently, in Japan, copper-bearing blue to green tourmaline is referred to as "Paraiba tourmaline," regardless of its origin. CuO: 3.569%, MnO: 0.315% (Request submitted to CGL for another stone; status available after 4:00 PM on 10/23)
