How to mine diamonds fast

•Branch-mine at Y=-59: dig a 2-high tunnel and space branches 3 blocks apart so every ore is exposed within reach.
•Below Y=-54 you hit large lava lakes — carry a water bucket and blocks, and never dig straight down into one.
•Use a Fortune III pickaxe: it averages ~2.2 diamonds per ore instead of 1, more than doubling a mining trip.
•Diamond ore emits no light and is fairly rare — clearing more blocks per second (Efficiency + Haste) matters more than luck.
