In response to a request, here's a pendant version of the design I used in the Seven-point Star Ring. The seven-pointed star is called a "heptagram." In Neopaganism, it is often called the Elven or Fairy star; the seven points represents 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 1 1/2" (37 mm).
