To get a sea lantern in Minecraft you need to combine 4 prismarine shards and 5 prismarine crystals in a crafting table. In this guide we will go through all the steps you need to follow from finding an ocean monument to crafting a sea lantern that will light up your surroundings.
Steps to Make a Sea Lantern in Minecraft
To create a sea lantern you will need to start by finding an ocean monument and defeating guardians or elder guardians.
Find an Ocean Monument
Ocean monuments can be found in deep ocean biomes such as:
- Deep Ocean
- Deep Frozen Ocean
- Deep Cold Ocean
- Deep Lukewarm Ocean
They are large structures made of prismarine where guardians and elder guardians spawn and will attack you during exploration. The easiest way to find a monument is by exploring oceans with a boat but you can also get a map from a cartographer villager which will show you the exact location. It is worth preparing before going underwater by using a water breathing potion.

Get 4 Prismarine Shards and 5 Prismarine Crystals
Prismarine shards can be obtained by defeating guardians and elder guardians in an ocean monument as they are their main drop.

Prismarine crystals have a lower chance to drop from these mobs but you can also get them by breaking sea lanterns without using a Silk Touch tool. Additionally prismarine crystals can be found in buried treasure so it is worth searching for them during exploration.

Craft a Sea Lantern
The final step is crafting a sea lantern in a crafting table. Simply combine 4 prismarine shards with 5 prismarine crystals and you are done.

From now on you will have a block that emits the highest light level and perfectly decorates your underwater builds.
