Crocidolite

 

a mineral, a blue asbestiform variety of the alkaline amphibole mineral riebeckite. Crocidolite occurs in metamorphic shales, forming pockets and veins. Large quantities of crocidolite (in veins) are located near Griquatown and in northeastern Transvaal (South Africa). In the USSR crocidolite deposits are found in the vicinity of Krivoi Rog and in the Urals (the Moiva River in Cherdyn’ Raion). Opal and quartz pseudomorphs after crocidolite are characterized by a beautiful silky luster and are used in jewelry-making as tigereye (golden brown) or hawk’s-eye (light blue).
