We understand. Finding diamonds can be a problem. Some map seeds are just plain bad for naturally generating diamonds near your spawn point, and you want to get to the Nether early so you can brew those potions. It's a dangerous world without potions! You're in luck. The guide below will tell you how to create a nether portal without diamonds.
How to Create a Nether Portal with Lava and Water in Minecraft
Whatever your reason, this is a small hack that takes advantage of game mechanics. That's how the pros play! They find the clever tricks to give them the edge and get them the best loot before anyone else. Let's go through the steps; There are not a lot!
Step One: Get Iron and Water
You are going to need at least seven iron to complete this task since you first need to craft two buckets and a flint and steel. When you've crafted one of your buckets, go ahead and fill it with water. You only need a bucket of water for the rest. Once you reach this point, you just need to research a bit.
Step two: build a wall near a lava pool
Lava pools aren't too rare, so you should be able to find one in just a few minutes. The only catch is that there must be at least 10 lava source blocks in the pool. With anything less than that, you won't be able to create a full nether portal. Once you find a lava pool, walk at least 15 blocks. It's best to build it this far, so your water doesn't accidentally spill into the lava pool and turn it into obsidian. Build a wall four blocks wide by five blocks high and remove the two blocks in front of the wall.

Third step: create the portal!
Imitate the image above to create your portal. First, make sure both buckets are side by side on your item bar so you can quickly switch between them. Then fill the empty bucket with lava. Fill the two holes in the floor with lava, then place water against the wall above them. This will turn lava blocks into obsidian blocks! Continue this process for each location to complete the Nether Portal. The image below is a good example.
Once you've done this for 10 spaces, you'll be ready to use the Flint and Steel on the Obsidian and light your Nether Portal. Hope you saved some time by not looking for diamonds! You may be in a rush, but make sure you don't run into the Nether!
