Butterfly Collar Jewelry Set

Butterfly Collar Jewelry Set Collar necklace, cuff bracelet and dangle earring set. Pattern looks like the wing of a butterfly. Likely 1970s or so. Unmarked, so unsure on maker or material. Sort of a brass look but I am unsure if they are actually brass or not. Very good preloved condition, no issues to note , normal signs of previous use. New to Poshmark?
