Vintage Chunky Gold Necklace w/Elephant Head Pendant

This is truly a statement necklace for all of you elephant fans. Not sure what kind of metal this is but it is a gold color. There are some serpents on the necklace above the Elephant Pendant. Got this from an estate sale and the lady who lived in the house used to work for a theater company. I’m pretty sure this is vintage but there are no markings or labels on the necklace Circa 1970’s
