NWOT Paua shell pendant necklace

NWOT Paua shell pendant necklace Classic piece for any time but PERFECT for summer: Amazing Blue - green - teal iridescent swirls from the shell. Can see the backing on the reverse. Silver tone 3D setting framed by 7 tiny “diamonds”, silver abstract filigree-like swirls and claws. (Setting is NOT Sterling silver) Pretty flat cable chain: 18”, 1 mm. NO HALLMARKS. (But don’t throw it away. It looks like the same chain, but smaller, from our zodiac pendants which are stamped as silver) Vintage c. 1990s. On original packaging. So shiny and bright: mint condition. Sorry, I don’t remember the name of the importer that we bought it from.
