Description

Prismarine Crystals are a luminous aquatic item added to Minecraft in Java Edition 1.8, dropped by guardians and elder guardians inside ocean monuments. Mining a Sea Lantern with any tool that lacks Silk Touch yields 2–3 Prismarine Crystals, and the Fortune enchantment raises that drop to a maximum of 5. Prismarine Crystals have a pale teal, glittering texture that sets them apart from the rougher Prismarine Shards collected in the same underwater ruins.

Prismarine Crystals are most valued for crafting Sea Lanterns: place five Prismarine Crystals in a plus shape around four prismarine shards to produce one Sea Lantern that emits light level 15. Because guardians respawn inside ocean monuments, Prismarine Crystals are fully renewable, giving builders a steady supply for underwater bases, aquatic-themed halls, and bright ceilings that never burn out like torches. Players chasing a clean ocean aesthetic rely on Prismarine Crystals to convert raw monument loot into permanent, waterproof light.

How to get and use Prismarine Crystals in Minecraft

  1. 1

    Find an ocean monument

    Locate an ocean monument in a deep ocean biome; these large structures are the only natural source of Prismarine Crystals.

  2. 2

    Defeat guardians

    Kill guardians and elder guardians patrolling the monument — each guardian drops 0–1 Prismarine Crystals, increased by the Looting enchantment.

  3. 3

    Mine Sea Lanterns

    Break the monument's Sea Lanterns with a tool that has no Silk Touch to drop 2–3 Prismarine Crystals each, or up to 5 with Fortune.

  4. 4

    Craft a Sea Lantern

    Arrange five Prismarine Crystals in a plus shape around four prismarine shards on the crafting table to make a Sea Lantern.

Tip

Use Silk Touch to collect whole Sea Lanterns instead of crystals; reserve Fortune tools for harvesting extra Prismarine Crystals.
