A Diamond Gemstone is obtained after smelting Diamond ore in a furnace. Diamond Gemstones can be used to make diamond tools. Diamond tools (excluding pickaxes which can be tipped with different ores to make them stronger) are the strongest in the game. Due to diamond ore getting more scarce and diamond gemstones being used up through everyday use, shop exploits may be used to make money to buy diamond tools although it is againest the spirit of the game.
