Sea Lanterns: The Primary Use
Prismarine crystals serve one main purpose in Minecraft: crafting sea lanterns. You’ll need four prismarine crystals plus five prismarine shards to create these beautiful underwater light sources. Sea lanterns emit a light level of 15, making them as bright as glowstone but with a distinctive aquatic aesthetic that fits perfectly in ocean-themed builds.
How to Obtain Prismarine Crystals
Getting your hands on prismarine crystals requires venturing into ocean monuments or finding guardians and elder guardians. These hostile mobs drop 0-2 prismarine crystals when defeated, with the Looting enchantment increasing your chances of getting more drops. Elder guardians are particularly valuable since they’re guaranteed to drop crystals.
Why Sea Lanterns Matter
Sea lanterns aren’t just decorative—they’re incredibly practical for underwater construction projects. Unlike torches or other land-based light sources, sea lanterns work perfectly underwater without being destroyed by water blocks. They’re essential for:
- Illuminating underwater bases and tunnels
- Creating safe swimming areas free from hostile mob spawns
- Building stunning aquatic architectural features
- Providing reliable light sources in ocean monument raids
Limited but Valuable
While prismarine crystals currently have only one crafting recipe, their rarity makes them quite valuable. Many players wish Mojang would expand their uses, but for now, focus on collecting them whenever you encounter guardians. The crystals’ beautiful appearance and essential role in underwater lighting make them worth stockpiling for your next aquatic adventure or building project.
Whether you’re planning an underwater city or just need reliable ocean lighting, understanding prismarine crystal mechanics will enhance your Minecraft building experience.
TL;DR
Prismarine crystals are primarily used to craft sea lanterns in Minecraft, requiring 4 crystals and 5 prismarine shards. They’re obtained by defeating guardians and elder guardians in ocean monuments.
