Bastnäsite-(Ce), which has the chemical formula (Ce,RE)(CO3)(F,OH), and parisite-(Ce), or Ca(Ce,RE) 2(CO3) 3(F,OH)2, are cerium-dominant rare-earth (RE) carbonates. Although they very rarely form as crystals large and clean enough for faceting, one locality in Pakistan (Zagi or Zegi Mountain) has produced bastnäsite-(Ce) that has been faceted into stones up to 20 ct (Johnson, 1999; Obodda and Leavens, 2004). Gem-quality parisite-(Ce) has been reported very rarely, usually associated with Colombian emeralds such as those from Muzo (Henn et al., 1992). In fact, the mineral is named in honor of J. I. Paris, one of the first managers of the Muzo mine (Palache et al., 1963). This note reports on bastnäsite- (Ce) and parisite-(Ce) from Malawi’s Mt. Malosa, where these minerals occur as well-formed crystals that locally may contain clear, gem-quality portions (e.g., figure 1). One of the authors (AG) visited the deposit in 2002 for research purposes, and has documented the geology and mineralogy of the area in other publications (e.g., Guastoni et al., 2007, 2009).

当出现“自动出价”图标时，表示我们的系统正在根据用户的最高出价主动为用户出价。这可能看起来好像用户出价高于自己，但这只是系统更新出价以反映用户最高限制的结果。
