This is a collection of 9 pieces of Northwestern Mutual Life Insurance Co gold pins, tie tacks, and belt buckle. Photo 1 shows the karat value of each piece. Pieces 1,2 & 5 have stones in them and if I had to guess I’d say they were ruby, sapphire, and emerald. They’re all in excellent condition for their age. I can take more photos if requested. Thanks for looking.
