In Japan, any blue-to-green tourmaline containing copper is called Paraiba tourmaline, regardless of its origin. It is a gemstone that boasts enduring popularity for its vivid coloration.\u003cbr\u003eThis is a Paraiba tourmaline from Batalha, Brazil. It is characterized by an exquisite hue that leans more towards green than blue, almost reminiscent of grandidierite. It offers a different expression from the vivid blue Paraiba typically imagined. It is a 3.8mm round cut. The analysis results show 2.80% CuO (copper oxide) and 5.74% MnO (manganese oxide). Includes an identification report and analysis report from GRJ (Gem Research Japan).\u003cbr\u003e\u003cbr\u003e・Type: Loose stone (natural stone) \u003cbr\u003e・Stone name: \u003ca href=\"https:\/\/store.karatz.jp\/collections\/brazilparaibatourmaline\"\u003eBrazilian Paraiba Tourmaline\u003c\/a\u003e (\u003ca href=\"https:\/\/store.karatz.jp\/collections\/paraiba_tourmaline\"\u003eParaiba Tourmaline\u003c\/a\u003e) \u003cbr\u003e・Weight: 0.195ct \u003cbr\u003e・Size: 3.7×3.8mm \u003cbr\u003e・Shape: Round cut \u003cbr\u003e・Scratches\/Chips: S-A+ \u003cbr\u003e・Inclusions: A+ \u003cbr\u003e・Notes: Usually heated. \u003cbr\u003e　*Paraiba tourmaline is generally a heat-treated gemstone.
