Over thousands of years, a tradition has developed, associating certain
    gemstones with times of the year. It is likely that pagan beliefs associated
    the time of year of a person’s birth with certain characteristics. Pagan
    cultures are ones in which the believers tend to be in tune with nature and
    the earth’s cycles and seasons.  These pagan beliefs became incorporated
    into later religions including Judaism and Christianity.


    With the passing of time and fashions, different gemstones have been
    ascribed to different months. It is thought that, originally, color was the
    major attribute which determined a person’s birthstone.  During the 18th
    century, the connection between birthstones and particular months
    received a wave of popularity, and many different lists came into being.  In
    1937, the (British) National Association of Goldsmiths (N.A.G.), organized
    a uniform “official” list, which seems to have become, more or less,
    internationally recognized.
