Hola again, Göran. We did some search...and it is possibly a specular hematite
nodule.It surely comes from the Saharan deserts. In the search, could not find
a similar rounded nodule of specular hematite....it must be a very old one for
its wheathered and eroded nature.BTW.....NASA has an old article about hematite
and its probably location on Mars surface :
http://marsrovers.nasa.gov/spotlight/hematite01.html
....and......In the below link, there are lots of pictures of all kid of
hematite :

Anyway...this little specular hematite stone, will enhance our rock and mineral
collection.
Hasta la vista,
larense
