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.
Ribbon of Saint George
The symbolism of the orange and black (or yellow and black) is thought to represent fire and gunpowder of war, or the death and resurrection of Saint George, or the colours of the original Russian imperial coat of arms (black eagle on a golden background). Another theory is that it is, in fact, German in origin, derived from the or and sable stripe patterns found on the heraldry of the House of Ascania, from which Catherine II originated, or the County of Ballenstedt, the house's ancient demesne.
