Blocks of Diamond (also known as Diamond Blocks) are decorative mineral blocks that do not appear in normally generated maps. They are obtained by crafting nine Diamonds together in a 3x3 square in a crafting grid. They currently serve no crafting purpose,but they do help to create beacons and function only as a decorative block and as a means of storing diamonds in a compact fashion. Diamond blocks can only be mined successfully with an Iron or Diamond Pickaxe. They use the same texture on all six sides. They are thought to be one of, if not the, hardest item to acquire in-game with the exception of blocks requiring the Silk Touch enchantment.
