Blocks of diamond are created by placing 9 diamonds in a 3×3 square on a crafting table. They have no current crafting use, other than being able to be turned back into 9 diamonds. Blocks of diamond are often only used as decoration and to show off a player’s wealth on multiplayer servers.
They’re sometimes used to store more diamonds in a single stack, as a full stack of diamond blocks equals 9 full stacks of diamonds. But because diamonds are very rare, few players even have more than 64 unused diamonds.
An iron or diamond pickaxe is required to mine this block, using anything else will destroy this block and the 9 diamonds used to create it. Despite being solid diamond, blocks of diamond are easily destroyed by explosions. They have the same blast resistance as stone blocks.
