Later the twelve gems were linked with the twelve signs of the zodiac and thus came to be associated with the months of the year. In the first century A.D. the historian Flavius Josephus traced the connection between the breastplate, the twelve months of the year, and the zodiac signs and wrote: "And for the twelve stones, whether we understand by them the months or the twelve signs of what the Greeks call the zodiac, we shall not be mistaken in their meaning."
While an astrologer convinced Elizabeth I of England and Mary, Queen of Scots that pearls were unlucky for them, Henry VIII was persuaded in the opposite direction concerning rubies! Generally speaking, gem stones symbolize positive, healing qualities. Certainly this is true of birthstones.
At first all twelve stones were worn in rotation by the same person in the belief that this was the way to ensure maximum benefit from each stone's qualities. For instance, Catherine de Medici wore a girdle set with twelve stone to derive the utmost benefit. The actual wearing of the birthstone appropriate for one's month of birth, however, is believed to have originated in the eighteenth century in Poland when gem traders settled there.
