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.
Samani
The growing of samani () - green sprouting wheat - is the most sacred Novruz ceremony as the herald of spring. Sprouting samani symbolises sowing and a rich harvest, it represents grain, bread, increase and abundance.
Grain and abundance is a pledge of life, existence, the most vital material necessity for life. People have always grown samani from wheat, barley, peas, lentils or other grains in copper dishes; they have always revered it and rejoiced at its sprouting.
