There is a gemstone with specific meaning to you. It depends in which month you were born.

A gemstone which is associated with a specific month in the Gregorian Calendar is called a “BIRTHSTONE.”

The tradition of birthstones stems from the 12 gems set in the breastplate of Aaron, the Hebrew high priest. These gems were associated with the 12 tribes of Judea and later with the 12 Zodiac signs.

In the eighth and ninth centuries, religious leaders associated a particular gemstone with each of the 12 apostles and it became the norm to keep 12 stones and wear one a month. Centuries later it became a practice to wear only the one birthstone. Different cultures use different gemstones and some believe that a specific gemstone imparts specific human emotions and characteristics to the wearer.

In 1912, in an effort to standardize birthstones, the US Association of Jewellers published a list of birthstones that was accepted by most western cultures. Changing fashions and new gem discoveries resulted in regular changes to the list. The latest was the addition of tanzanite as a birthstone for December.
