{"title":"Chlorite","description":"\u003cp\u003e\u003cstrong\u003eChlorite\u003c\/strong\u003e is a name collectors know well: a group of over ten closely related phyllosilicate minerals, including \u003cstrong\u003eclinochlore\u003c\/strong\u003e, \u003cstrong\u003echamosite\u003c\/strong\u003e, \u003cstrong\u003ecookeite\u003c\/strong\u003e, and \u003cstrong\u003epennantite\u003c\/strong\u003e, unified by a micaceous, foliated structure and a soapy, greasy feel. Its name comes from the Greek for \"green,\" and indeed most specimens range from pale to deep bottle-green, though the chromium-rich variety \u003cstrong\u003ekämmererite\u003c\/strong\u003e shows a striking violet-pink instead. Chlorite forms in low-grade metamorphic environments, greenschists, phyllites, and hydrothermal veins, and it commonly grows with epidote, actinolite, quartz, and calcite.\u003c\/p\u003e\u003cp\u003eClassic collector-grade chlorite comes from the \u003cstrong\u003eMaderanertal\u003c\/strong\u003e in Uri, Switzerland, prized for its shimmering green coatings on quartz and adularia that produce ghostly phantom crystals. In the United States, well-formed crystals are documented from the \u003cstrong\u003eGreen Mountain Mine\u003c\/strong\u003e in Yancey County, North Carolina, while the \u003cstrong\u003eTilly Foster Mine\u003c\/strong\u003e in Putnam County, New York, is famous for unusual chlorite pseudomorphs after other minerals. Additional notable pieces come from Zillertal in Tyrol, Austria, the New Idria District in California, and classic Alpine-cleft localities across the Alps.\u003c\/p\u003e\u003cp\u003eThough often dismissed as an ordinary green coating on more glamorous minerals like quartz, adularia, or laumontite, fine chlorite specimens, especially sharp pseudohexagonal crystals, rosettes, and colorful kämmererite plates, are genuinely sought after by systematic and thumbnail collectors alike. Its role as a diagnostic mineral of the greenschist facies also makes it a favorite teaching specimen for students of metamorphic petrology.\u003c\/p\u003e","products":[{"product_id":"lz-quartz-chlorite-switzerland-0","title":"QUARTZ with CHLORITE  – Alpine Crystal with CLAY INCLUSIONS from Switzerland","description":"\u003cp\u003eNatural Quartz crystal with green Chlorite and clay inclusions from Val Russein, Disentis, Surselva, Grisons, Switzerland.
