It is found worldwide in granites, pegmatites and metamorphic rocks. Tourmaline is strongly piezoelectric and pyroelectric: when rubbed or heated it develops a small electric charge and attracts dust. Sources include Brazil, the USA, parts of Africa, Pakistan and Afghanistan.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAuturaSol Standard\u003c\/strong\u003e\u003cbr\u003e\nEach natural stone is selected for its authenticity, geological integrity, and energetic clarity.
