Here is a super sleek and simple modernist necklace by the renowned Danish siversmithy Anton Michelsen, made in their Swedish subsidiary. I do not know for certain who the designer was, but I suspect it may have been Erik Fleming of the esteemed Swedish Borgila silver company, with whom Michelsen cooperated during the 1950s. I have seen some Borgila pieces with the same oval link design.
