The answer is no. A person who is not a Freemason, should not wear Masonic jewelry ( This includes masonic baseball caps, belt buckles, T-Shirts,etc). Our fraternity is limited to men of good character, who have completed the process to become a Mason.
You should not wear a badge, if you are not a policeman. Same idea.
If you have any masonic jewelry, that you wish to dispose of, I suggest e-bay.
