It is by far the most abundant tourmaline species, accounting for the vast majority of material in this mineral family, and is prized for its opaque jet-black luster, sharp trigonal prisms, and striated crystal faces that often terminate in glassy, well-formed points.\u003c\/p\u003e\u003cp\u003eClassic material comes from the granite pegmatites of \u003cstrong\u003eMinas Gerais\u003c\/strong\u003e, Brazil, including Governador Valadares and São José da Safira, while exceptional lustrous, multi-terminated clusters are sourced from the \u003cstrong\u003eErongo\u003c\/strong\u003e region of Namibia. Fine crystals also reach collectors from \u003cstrong\u003eSkardu\u003c\/strong\u003e and \u003cstrong\u003eGilgit\u003c\/strong\u003e in Pakistan, the \u003cstrong\u003eSahatany Valley\u003c\/strong\u003e in Madagascar, Dolní Bory in the Czech Republic, and \u003cstrong\u003eElba Island\u003c\/strong\u003e, Italy — historic ground shared with its gem cousin \u003cstrong\u003eelbaite\u003c\/strong\u003e. In the United States, notable schorl comes from Maine's Oxford County pegmatites and San Diego County, California.\u003c\/p\u003e\u003cp\u003eCollectors seek schorl for its striking contrast against host minerals like smoky \u003cstrong\u003equartz\u003c\/strong\u003e, feldspar, and albite, its needle-like inclusions forming ornamental \u003cstrong\u003etourmalinated quartz\u003c\/strong\u003e, and its role as a benchmark species within the wider tourmaline group alongside dravite and elbaite. Sharp terminations, radiating sprays, and large aesthetic clusters command the highest interest among specimen collectors and mineralogists alike.\u003c\/p\u003e","products":[{"product_id":"black-tourmaline-raw-crystal","title":"Black Tourmaline Raw Crystal","description":"\u003cp\u003ePowerful natural black tourmaline crystal from Pakistan, featuring deep black color and raw natural formation.
