At first, I was baffled when I heard about masonic jewelry, so I made a very brief research about it. Freemasonry according to E-How.com is a secret society or organization that had their own tradition, rituals, signs and symbols. It's a brotherhood organization that dates back to 17th century and if you're a member you'll be proud to wear one of those masonic rings that can symbolize brotherhood. These rings symbolizes you're a part of the group and proud to be one. Famous members are Julius Ceasar, Michaelangelo and lots more. I even heard that Obama is a member as well.
Just some of the many masonic rings that you can find these days and each ring can distinguish the social standing of a member.
