M250hc A nice specimen of natural Copper from Keweenaw Peninsula, Michigan. This
is natural native copper which has been removed from the matrix rock which
was surrounding it. It is the natural formation just as it
formed in the rock. It measures 4 1/4" x 1 3/4" x 3/4".
Copper is a reddish colored metal with a high electrical and thermal
conductivity. It has its characteristic color because it reflects red
and orange light and absorbs other frequencies in the visible spectrum due
to its band structure. It is in the same family as Silver and Gold and
is a malleable metal. It is beautiful natural or polished.

Ammonites are extinct members of the cephalopod group of mollusks. Only
a limited number of species have survived to the present day which includes
the squid and the chambered nautilus. Ammonites had a multi-chambered shell,
and added more chambers as it grew, always living in the outer chamber.
They lived in the Cretaceous period some 63 to 130 million years ago.
