Gold

Gold is a metallic substance used for minting money and for creating various articles of great value. The possession of gold among humans is commonly seen as a symbol of status and wealth.

In mainstream media
As with money, the Smurfs have no need for gold, as they put their value in friendships and family more than personal possessions. However, the Smurfs have been seen using gold in the creation of other things, such as King Smurf's gold suit and the musical instruments made from the gold coins that were once used by the Smurfs in "The Finance Smurf" when the title character had introduced a capitalist monetary system into their society.

The Smurfs' main adversary, Gargamel, continually pursues them in his constant quest for creating the formula that would turn base metals into gold. The amount of Smurfs needed for the formula's completion, however, varies depending on the story, though it's usually six Smurfs. In "All That Glitters Isn't Smurf", Papa Smurf used Gargamel's lust for gold against him by creating a mountain of fake gold coins using locks of Smurfette's hair to create them.

Michael, the leprechaun who lives in the Smurf Forest, usually carries a pot of gold with him. In "How To Smurf A Rainbow", when Papa Smurf lacked enough yellow items in his spell to create a complete rainbow, Michael allowed the use of his gold to complete the rainbow.
