Vintage Necklace with Crystals

16½" necklace containing 55 crystals. I am the original owner. I received this as a gift over 45 years ago and never have put it on, it went straight into my jewelry box. It's very pretty, just not what I wear. It's time for someone to enjoy this piece! The necklace has no markings. It is not silver or white gold. I do not know the age of the necklace, it could be older than 45 years old. It is a lovely, well made, crafted piece. I have not seen a link similar to this before, large links were crafted to hang the crystals, it is very unusual. Since the piece did not tarnish I would assume it is made of a stainless steel.
