Northwest Africa 2733 was purchased in 2007 from a
meteorite dealer in Dakhla, Morocco. The stone was a
single whole piece weighing 278.7g. The meteorite was classified
as a very rare Carbonaceous Chondrite, CO3.6 of which only eight
other meteorites have been classified as. Three of those are
Antarctic finds and another is the 2006 Norwegian fall, Moss.
The other three are NWA specimens. The exterior of the stone has
a slightly desert varnished exterior but a sea of tiny pale
chondrules in clearly visible through that. The cut face
reflects the same and displays as a beautiful example of a primitive
type-3 carbonaceous chondrite. There is also a very unusual
feature on the bottom of this stone where a deep ridge appears
to have been ablated out during atmospheric entry. The 243.2g Main Mass below
is part of the Meteorites Australia Collection (MA.07.0020).
