Silver
Silver is a chemical element with symbol Ag (from the Latin "", derived from the Proto-Indo-European "h₂erǵ": "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.
Mărțișor
George Coşbuc stated that Mărțișor is a symbol of fire and light, and of the Sun. The colours and the traditional silver coin hung from the thread are associated with the sun. White, the colour of silver, is a symbol of power and strength. The round form of the coin is also reminiscent of the Sun, while silver is associated with the Moon. These are just a few of the reasons why the Mărțișor is a sacred amulet.
