Various geodes
Minerals are items that can be found in The Mines and the Skull Cavern. Most minerals are acquired from geodes after having Clint process them. Some are found on the ground and some (in the case of gems and resources) can be mined from nodes, which are also found in the Quarry. They can also sometimes be acquired as monster drops, as gifts from Villagers, or from the Statue of Endless Fortune. stardew valley wiki
