Disco Beaded Blue Black Gray Necklace Collar

This big disco retro style beaded necklace covers a good portion of your front! Beading is gray, blue and black. Lobster claw clasp. Adjustable by clasping to different part of chain. There is a photo of the knot in the chain, which doesn't affect wearing it. I just couldn't get it out. I'm pretty sure I purchased this in the very late 90's or early 2000's at latest. I might have worn it once. Measures about 21 1/2" shown in ruler photo (ruler cut off in photo, but shows most of it).
