Spawn near a village with NPCs and go to these coordinates 608 63 -424. Dig deep and soon you will arrive at an abandoned mine-shaft. You will find a hatch that you need to open and there are 6 diamonds right there ready to be mined.
Now, you can go back up to the village and check out the blacksmith’s chest. It includes: 5 iron ingots, a golden ingot, a saddle, iron chest-plate, iron boots, and an iron sword with +6 attack damage. It’s a great seed, check it out.
