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.
Herefordshire
The red colouring ("gules") of the shield is taken from the arms of the City of Hereford. The red colour also represents the red earth of Herefordshire. The silver and blue wave across the centre of the shield represents the River Wye. The lions that form parts of the arms, crest and supporters are also taken from Hereford's arms. The agricultural produce of Herefordshire is represented by the bull's head, fleece, hops and apples. The talbot dog comes from the heraldry of the Talbot family, Marcher Lords of Shrewsbury and also from that of Viscount Hereford.
