Tiffany is a girl's name of Greek origin. An anglicized version of Theophania, it means "revelation of God" and is a popular choice among Christians. This name was traditionally given to girls born on the Feast of the Epiphany on January 6 before gaining a broader appeal with secular families. In the US, Tiffany climbed the name charts in the 1980s due to its association with the renowned jewelry business Tiffany & Co. Whether you want to honor your faith or treat your daughter like a precious gem, Tiffany is a sweet and stylish choice.
