Re: This necklace is beautiful and rare ! Yes some of these came with hang tags with no stamping and some were hand scribed on the main stone holding plate as well. the exact era this was made is very early 1980 to 1982. It was not surprising to find a necklace of this rarity in the Sacs fifth Ave Department store based in New York. Who new this would be such a sought after piece in this Era ? you're very lucky to have this. Great Find ! Enjoy this necklace as it is likely you will not find a duplicate of this particular necklace. M.g.
