Butterfly Chain Drop Collar

Black on black stops reading after about a metre, which is roughly the distance people keep at a party. This breaks it with one red butterfly - long faceted stones set into dark open wings - sitting under a plain flat band, with fine chains swagged below and small teardrops hanging off the loops. One chain runs longer than the others and drops to the top of the neckline. The band stays plain, so the butterfly competes with nothing.
