Diamond Ore – Official Minecraft Wiki

Diamond ore can generate in the Overworld in the form of blobs. Diamond ore attempts to generate 1 time per chunk in blobs of 0-10 ore, in layers 1 to 16 in all biomes. If multiple blobs spawn directly adjacent, it is possible to have a "singular blob" with more than 10 diamond ore. On average they generate 3.7 ores per chunk.


This means that in this ore deposit, the copper is concentrated 857 times above the average crustal abundance. Ore deposits consist of rocks called ores. An ore is a mixture of valuable ore minerals and low-value gangue-minerals. Most ore minerals are compounds of either oxygen (e.g. metal oxides) or sulfur (metal sulphides).
