It is made out of pewter. Pewter is marginally darker than silver, does not tarnish, cannot rust and does not stain or deteriorate. The biggest difference between the two metals, apart from the slightly darker shade, is that pewter, unlike silver, is not a precious metal. However, it is ranked as the fourth most precious metal in the world, characterized by its relatively soft nature. Similar to silver or gold, the metal of the pendant becomes less shiny with regular wear.
