Minecraft wiki entry for Nether_survival, associated text: Some things can't be produced in the Nether, and need to be brought in from the Overworld: There are no ores, besides nether quartz ore, ancient debris, and nether gold ore. There is no diamond unless you import it from the overworld or you find it in bastion remnant or nether fortress chests. Emerald, iron, redstone and lapis lazuli are renewable through villagers, and gold is renewable through zombified piglins. Iron is also renewable from bartering, as well as water, though it has to be stored in cauldrons. Coal is renewable from wither skeletons or smelting overworld wood. Blackstone can be used as an alternative to cobblestone. You can get the Pigstep music disc and the snout banner pattern from a bastion remnant, and diamonds and horse armor can be obtained through a nether fortress.
