70's Gold and Green Stone Necklace

Super cool 1970's necklace - 16" snake chain is fairly short, so this could also be considered a choker, depending on your neck size. You could also easily change out the chain for another one, if you prefer. I think this would also look great on a super long chain. Round gold colored pendant with a green tumbled stone - looks to be adventurine - set in the pendant. I'm guessing this was a custom made piece, it's very unique and so lovely!There are no markings on the necklace or pendant, so I can not say for certain what the materials are. Pendant measures 1.25" in diameter. This piece is in very good to excellent vintage condition. I could find no major flaws or issues.
