RARE FIND New vintage beaded necklace (black-orange-cream-gold)

RARE FIND New vintage giant beaded statement necklace (black-orange-cream-gold) Hard to describe: reminds me of acrylic - resin - epoxy pours and blown glass (but it’s not stone, glass, plastic). Nice cool texture like tile but not too heavy. Gorgeous organic, globby patterns like lava lamps. Psychedelic. Sort of like tonal millefiori art. 28” long, twist metal closure, thick stiff string inside. New. Probably ceramic. Not stone. C. 1970s.
