Gold

This well-known pure metal is the softest of workable metallic substances, and one of the best conductors among them. Despite its high value, it is relatively common and is favored for use in ornamentation in the making of magical items, often being used as an inlay in graven runes or inscriptions, where meld magics can keep it from being damaged or falling out through rough handling. Gold has the important ability to hold multiple enchantments, even conflicting ones, and keep them from affecting each other or the stability of the gold-adorned item.
