Medium stones are most commonly acquired from a dig event. A dig hole produces both cuttable stones and medium stones. Early in the dig, the hole produces a greater ratio of cuttable stones to medium stones. The longer the hole is open, the more Medium Stones are produced.
Medium stones can also, rarely, be found in the wild. When the game server starts, a number of medium stones are placed randomly across the map.
