Oh my, finally found some!
Diamond ore is generally considered to be the most valuable and elusive block in the game. It can be found inside stone blocks very deep underground, and you may often find lava in its proximity. It can be mined for a diamond gem using an iron pickaxe or better. The diamond gems can be used right away in a workbench to craft diamond tools, which are the best in the game. This, along with Coal and Redstone, do not require any smelting and can be used immediately. You can also create diamond blocks by crafting nine diamond gems together in a 3x3 square using the workbench.
It can not be placed in creative mode as of version 0.30 and it drops 1 diamond gem in Indev and Infdev.
