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.

Empath: The Luckiest Smurf stories
As in mainstream media, gold is a rather useless commodity among in the Smurfs in the EMPATH: The Luckiest Smurf story series. However, the Smurf Village version of Elysium that was created by Ares the god of war as a lure for Empath had Smurf houses that were made entirely of gold. Also, the Smurfic Games Tournament medals created by Sculptor and Smithy were made in gold, silver, and bronze. In fitting with the theme of Tapper's Song Of Solomon adaptation setting in the Imaginarium, Empath's Smurf suit in the role of King Solomon is made of gold.

Hero Stories
In the HERO: The Guardian Smurf story series, Hero Smurf wears a Smurf suit with a colour that looks identical to gold, and there is also a Power Stone with this colour.

RDK Stories/Expanded AU
Within The Reluctant Dark Knight series, which crosses over with the Expanded Animated Universe, gold is a source of monetary value for humans and some other species, including Gnomes and dragons, who hoard it for themselves as an establishment of higher status.

Falla wears a ruby-studded gold bracelet as a symbol of her royal status while she is away from her Castle Cye. Princess Savina wears a gold pendant on her headband, but may wear more jewelry for special occasions, as will Falla.

Smurfs
The Smurfs have no need for gold, but they are able to recognize its value and, if they find any, tend to share it with their human friends. Moxette, however, wears a small gold clasp on the strap of her dress.

Sprites
Karma wears a gold pendant with an engraved word that can only be translated by her true love. In her past life, Maeve was adorned with gold on her outfit to allure people into giving her master money, which was a never-ending battle of paying her debt to him. With help from Tebuli and Ernie, she used a genie wish to give her master "a mountain of gold," which then freed her.
