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).

Why are users outbidding themselves?

When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.

When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.
