Amazing Beaded Vintage Sweater

It's hard to capture how beautiful this sweater is! I can't find too much detail on this, but I feel like it might be from the 80s. This is a black sweater with beautiful beading. The beading almost has an "oil slick" look to it. In great condition with some signs of wear, see photos for wear and condition. No size tag, but I would say this could fit from a S-L? since it is a sweater with a little stretch. I can provide measurements upon request.
