Malachite Wire Wrapped Oxidized Copper Brooch
This is a Brooch, not a pendant.
The stone is a Malachite.
The wire is solid copper that has been oxidized and polished for an antique look. Please note that copper naturally darkens with age and if necessary may be cleaned to lighten it back up, a polishing pad is included. The last photo shows back of the pendant, it is next to a ruler for size comparison.
