Onyx Agate Oxidized Copper Pendant

The main bead/stone is Onyx Agate. The little bottom bead is an unknown stone. 

The wire is solid copper that has been oxidized and polished for an antique look. The cord necklace is included, it is nylon and is adjustable roughly 18"-20". Please note that copper naturally darkens with age and if necessary may be cleaned to lighten it back up.  The last photo shows back of the pendant, it is next to a ruler for size comparison.
