The seven-pointed star is called a "heptagram." In Neopaganism, it is often called the Elven or Fairy star; the seven points represent air, fire, water, earth, above, below, and center. In Christianity, the heptagram represents the seven days of creation.
Tip: the points of the star are sharp; be careful! You may want to file them down. The height of the heptagram is about 3/4" (20 mm).
