This is a very sweet choker style necklace.   The chain is black and can be adjusted with the extender that measures 8cm.  The chain in total measures 38cm.

In the middle of the choker there are some beautiful very dark bronze square pieces with a black crystal attached.  This section of the necklace measures 9cm long.  Each square measures 1cm.  They are connected with a small bead.  The section is articulated with a small black spacer bead connected to metal hoops.

It is in perfect condition.  It is by Peter Lang.
