It is entirely permitted, for the female dependents of Masons to wear such jewelry. There are "Mrs. Mason" pendants, and "Blue Slipper" pins, available as well. My wife travels internationally, frequently. I got her a "Mrs. Mason" pin, and told her, that if she ever gets into a hassle, to seek out a Mason, and ask for help, as he is pledged to render assistance. You should get a Masonic sticker for the window of your wife's/daughter's vehicle as well.
