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 3 1/2" x 2 3/4" x 1/2".
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.
