The dodecagram, or twelve pointed star, is one of the popular symbols of Hellenism. The twelve points represent the twelve Olympic Gods of ancient Greece. A dodecagram is a star polygon that has 12 vertices, or a 12-pointed star. The name "dodecagram" combines the numeral prefix dodeca- with the Greek suffix -gram. The -gram suffix means a line. All materials in my beautiful Dodecagram pendant necklace are made from pure 304 Stainless steel. Stainless is hypo-allergenic, non-tarnishing, strong, shiny and durable.
