Vintage Statement Necklace Very Large and Chunky Black & Green

Measures about about 19.5" long including extender. Very very chunky. Some time of plastic. Some areas are not quite as glossy as other due to wear/age. Green is like a muted lime shade.

Preowned vintage necklace, sold as shown - I am unsure of material type(s) because of this. Pictures show different angles for you to review - while I attempt to note any defects, some tarnish/signs of wear may be visible that are not otherwise stated.
