Talk:Diamond Ore

Natural generation
Under this specific section is following statement "Diamond ore only appears at Y level 16 and below, and can be found in veins of 3–8...". Are there not veins of 9? RobinEH (talk) 11:15, 1 August 2015 (UTC)

9 and 10! But the page now reads 1-12 which I doubt, does anybody have the knowledge to clarify if veins of more than 10 are possible? (without merging 2 veins.) Hexalobular 1 Jan 2016

Veins with 10 ore can be found in seed "-8246714680227619312" (without citation marks of course) at 377/10/1, 52/8/360, 1066/9/898, 593/12/1023, 312/9/307 and -22/8/-59 (and 9-ore veins at 361/11/-19, 77/12/-487, 1166/12/1374, 1096/9/1270, 1198/13/1266, 769/10/930, 170/7/586, 315/14/284, 331/11/1088, 138/9/944 and -475/12/372) All of these fit into a standard shape of a 2X2X2 cube with an extra ore block on top and another on the bottom (only 1 extra block for the 9 block veins) Screenshots at https://drive.google.com/folderview?id=0B5c6qRTAo-4nSjI2WUhzOXprQkE&usp=sharing Hexalobular (talk) 10:09, 4 January 2016 (UTC)


 * Could these be a result of viens combining? -PancakeIdentity (talk) 00:02, 23 August 2016 (UTC)

No, they would be more random and wouldn't all fit in the same standard shape. --Hexalobular (talk) 01:54, 28 August 2016 (UTC)

We need a better way to refer to specified vein size and actual vein size. I think that it is causing confusion. In the page it says 0-8 vein size but the vein size according to the mineral vein is fixed at 8. Furthermore, the size parameter does not correspond with the max amount of diamonds that should be spawned. Max amount is 10. So, if we want to put a range it should be 0-10. Correct?

Minecraft is still generating veins of diamond ore with 10 ores in Java 1.16.1 and people are still misguidedly changing the Wiki to read 1-8. Diamond veins with 10 ores: Java 1.16.1, Vanilla, Seed:-597086656834133 Large Biomes -10/9/-404, -454/11/119, -1/9/408, -67/13/434, -975/5/9, -867/6/86, -496/13/-133, -718/7/-135, -824/10/-70 all of these match the standard vein shape, 1 was straddling the chunk border, 4 had a 1 block gap, the rest had 2, 3, 5 and 6 block gaps to the closest border. I have also found 29 9 ore veins that also all match the standard shape. Flying around underground over a few thousand chunks with everything except diamond ore removed I have seen exactly no sign of any merged veins, I did find 2 places where 2 veins were touching but they were unmerged, taking up a total of 8 columns, 4 per vein. It beggars belief that all of those 9-10 ore veins could be the result of invisible vein mergers with none of them nor innumerable veins with fewer ores showing any signs of mergers, all of them fitting the standard shape. There must be some merged veins but they are obviously WAY too rare to explain all of the 9-10 ore veins! --Hexalobular (talk) 17:25, 30 June 2020 (UTC)

A diamond vein can't stick out of its chunk by more than 1 block, any merged veins must therefore be in contact with a chunk border. So any 9 or 10 ore veins that don't contact the chunk borders must be single veins! They can't be explained by mergers! --Hexalobular (talk) 08:44, 2 July 2020 (UTC)

Found 5 veins with 9 ores in Bedrock 1.16.1 (Win-10) Seed:16 328/9/2,  133/10/-78,  99/6/-106,  109/9/-150,  100/9/-157 --Hexalobular (talk) 16:11, 9 July 2020 (UTC) And 1 with 10 ores, 400/11/-602 --Hexalobular (talk) 18:14, 9 July 2020 (UTC)

I ran an external test with 1,000,000 cycles for this and was given an effective range of 2-8 ores for the given value of 8 as diamond has. Missing stone from carvers and the like would explain smaller veins of size 1, but doesn't explain > 8 size veins.

@Scimiguy What test? Did you look at actual veins or the value of a variable in the code? I don't understand the code but I have it from a good source, TheMasterCaver in minecraftforum.net, that the variable used doesn't set a max size but is used in some other way during the generation. Did you look at my 10 ore veins in game? Hexalobular

Clarification for generating 'once per chunk'
Under "Natural Generation", it mentions that diamonds will spawn once per chunk, but it isn't clear if it means a 16x256x16 space (16 in x and z, but extending all of the y values), or a 16x16x16 space (16 in all directions, sometimes called a 'sub-chunk'). This leads to some more confusion because the Chunk page strictly defines a chunk as 16x256x16, but then in the the in-game F3 menu defines a chunk in terms of 16x16x16 and the chunk coords are defined as "x%16 y%16 z%16 in x//16 y//16 z//16", clearly showing that the in-game definition of a chunk is 16x16x16. So if the number of "once per chunk" was determined by looking at minecraft's code/update logs/other official sources, it may follow that definition instead. If the numbers were determined experimentally, then it should be reflected such as "once per 16x256x16 chunk". Given that Diamonds spawn from 1-15, this could present the opportunity for diamonds to spawn twice as frequent as mentioned in the article. --Ximmrspyx (talk) 05:23, 22 June 2020 (UTC)

What? Surely 1-15 fits in the lowest subchunk, 0-15? --Hexalobular (talk) 11:18, 30 June 2020 (UTC)
