Diamond Ore

Diamond ore is a rare ore that generates deep underground, and is the only reliable source of diamonds.

Deepslate diamond ore is a variant found in the deepslate layer of the world, below y=0.

Natural generation


Diamond ore can generate in the Overworld in the form of mineral veins. Diamond ore attempts to generate 1 time per chunk in veins of 1-10 ore, between altitudes 1 and 16 (in layers 1-15), in all biomes. If multiple veins spawn directly adjacent, it is possible to have a "singular vein" with more than 10 diamond ore. On average they generate 3.7 ores per chunk. As of Java Edition 1.16.4, on average they generate 3.4 ores per chunk. As of Java Edition 21w10a, diamond ore now generates from Y=16 to Y=-63, the deeper one goes the more common it is, and has reduced air exposure.

Breaking
The diamond ore block itself (rather than its diamond drops) can be obtained by mining it with an iron, diamond or netherite pickaxe with the Silk Touch enchantment. When mined without Silk Touch, diamond ore drops a single diamond. The maximum amount of diamonds dropped can be increased with Fortune. Fortune I gives a $1/3$ chance for 2 diamonds, averaging 1.33 diamonds, Fortune II gives a 25% chance (each) to give 2 or 3 diamonds, averaging 1.75 diamonds, and Fortune III gives a 20% chance (each) to give 2, 3, or 4 diamonds, averaging 2.2 diamonds.

Note Blocks
Diamond ore can be placed under note blocks to produce "bass drum" sound.
