Silver

This relatively common valuable pure metal is known to the elves as “the sheath and shield of Art” because, of all metals, it is the most associated with and suitable for magic. Many dwarves use silver in various alloy formulae of their own devising or that have been handed down through clans for generations. Most of the beauty of metalwork down through the ages has been associated with the gleam and hue of mirror-polished, untarnished silver, and it has always been associated with the adornment of magical items.
