The most seductive metal of them all. Millions have died in attempting to feed the endless human thirst for gold. This soft metal is little use on its own, but is strikingly beautiful and very rare.
Gold is a very beautiful and expensive resource. Can sometimes be found off the bodies of raiders, as well as those who pop out of random cryptosleep caskets in buildings around the map, but the primary source is gold veins. You can sell gold to certain traders to get a staggering amount of cash, or craft it into golden sculptures that are perhaps the most valuable items in the game. It can also be used to create extremely beautiful furniture and structures.
Gold art and furniture is the best way to get that coveted "Beautiful Environment" mood bonus for your colonists, though this may be wasteful unless you are swimming in cash already and don't need much extra.
Colonists can suffer from a "High Expectations" mood debuff if your colony becomes too rich. Make sure you have plenty of mood-boosting effects to buffer against this before you start accumulating some real wealth.
