Meghan Markle was baptized by the Archbishop of Canterbury, since then she’s been wearing a new diamond cross bracelet. Many believe the bracelet she wears on her left hand is a baptism gift.
The bracelet is worn stacked with another diamond horizontal bar bracelet.
Markle was brought up Episcopalian but wasn’t required to convert to her future husband’s religion for their wedding. She did so to show respect to her future Grandmother-In-Law, Queen Elizabeth II.
Fortunately for Meghan the rules have become more lax over the years. Previously one would have to never have been married and must be from the Church of England.
