Prismarine Crystals

Prismarine crystals are the bright ingredient in sea lanterns and can be recovered from some existing fixtures.

SurvivalJava & Bedrock

What is Prismarine Crystals?

Prismarine crystals are distinct from prismarine shards. The two materials meet in the sea lantern recipe, which uses five crystals with four shards. The crystals are easy to mix up with the shards after clearing an ocean monument because their names share the same source block family.

Why players overlook it

A few crystals have no obvious role until you want sea lanterns. Players who light most rooms with torches may gather them during one ocean trip and leave them in storage indefinitely.

How to get it

  • Defeat guardians or elder guardians for a chance to collect crystals.
  • Break an existing sea lantern without Silk Touch to recover some crystals. Use Silk Touch if you want to keep the whole light instead.

What is it used for?

  • Craft sea lanterns with the crystals and shards. The finished blocks give strong, even illumination for floors or the underside of a roof.
  • Keep separate bins for crystals and shards if you are producing a large batch.

When it comes in handy

Before breaking lanterns from a monument, decide whether you need ingredients or the finished block. If you already have a Silk Touch tool, collecting the complete lantern avoids using more crystals and shards to rebuild it later.

Limitations

The shards are still needed for new lanterns. Breaking lanterns for crystals alone is not an efficient way to supply a project that already needs finished lights.

Editorial recommendation

Is it worth using?

Save crystals when sea lanterns suit the palette or you already have a guardian source. Keep finished lamps intact when possible.

Alternatives

Use glowstone or a different full-block light for a large project if monument loot would be the only source of prismarine materials.
