How to Get Prismarine Shards in Minecraft
Prismarine Shards TipsPrismarine Shards are one of Minecraft’s most location-locked resources — unlike most materials that can be found in multiple biomes or structures, Shards are tied entirely to Ocean Monuments and the Guardians inside them. This makes the Ocean Monument one of the most purposeful mid-game destinations: you go there for Shards, come away with Prismarine Crystals and Wet Sponges as bonuses, discover 8 hidden Gold Blocks, and potentially establish a Guardian farm for long-term Prismarine supply. The animated colour-cycling texture of Prismarine blocks makes them one of the most unique-looking building materials in the game — the slow green-to-teal-to-blue shift gives builds a living, underwater quality that static blocks can’t replicate. For ocean-themed megabuilds, a steady Prismarine Shard supply from a Guardian farm is often what separates a small ocean outpost from a full-scale underwater city. Pair the Prismarine guide and the Ocean Monument guide for the complete picture.FAQ
⚡ Quick Answer
How to Farm Prismarine ShardsPrismarine Shards drop exclusively from Guardians and Elder Guardians — the hostile fish-like mobs that spawn inside and around Ocean Monuments. Each Guardian drops 0–2 Prismarine Shards on death (up to 4 with Looting III). There is no other source. Find an Ocean Monument, kill the Guardians inside, and collect the shards — they’re used to craft Prismarine, Prismarine Bricks, and Sea Lanterns.
1
Find an Ocean Monument. Ocean Monuments are large underwater structures made of Prismarine that generate in Deep Ocean biomes. The easiest way to locate one is with the command /locate structure monument (Java) or /locate Monument (Bedrock). Without commands, explore Deep Ocean biomes — Monuments appear as large dark teal structures visible from the surface in clear water. A Buried Treasure Map or Ocean Explorer Map (bought from a Cartographer villager for Emeralds) also marks nearby monuments.
2
Prepare for underwater combat. Guardians deal up to 6.5 damage per hit and inflict Mining Fatigue III via Elder Guardians — dramatically slowing your mining speed. Before diving, brew a Potion of Water Breathing (Water Bottle + Nether Wart + Pufferfish) to breathe indefinitely underwater, and a Potion of Night Vision (Water Bottle + Nether Wart + Golden Carrot) since Ocean Monuments are very dark inside. Wear at least Diamond armor with Depth Strider III boots for faster underwater movement. A Sword with Smite does not apply to Guardians — use Sharpness V instead.
3
Kill Guardians to collect Prismarine Shards. Guardians spawn continuously inside and around Ocean Monuments as long as the monument exists. Each Guardian drops 0–2 Prismarine Shards and 0–1 Prismarine Crystals on death. Use a Sword with Looting III to increase the maximum drop to 4 Prismarine Shards per kill. Guardians also have a chance to drop raw fish (Cod or Salmon). Kill them as fast as possible — their laser attack builds up and deals heavy damage if you let it charge fully.
4
Kill the 3 Elder Guardians for extra shards and Monument loot. Every Ocean Monument contains exactly 3 Elder Guardians — one in each wing. Elder Guardians are much stronger (80 HP vs 30 HP for regular Guardians) and each drops 0–1 Prismarine Shards, 0–1 Prismarine Crystals, and a guaranteed Wet Sponge (extremely useful for draining water). Killing all 3 Elder Guardians also removes the permanent Mining Fatigue curse they inflict on nearby players. Use a Milk Bucket before entering to temporarily clear Mining Fatigue.
5
Build a Guardian farm for bulk Prismarine Shards. For large-scale Prismarine farming, build a Guardian farm at the Ocean Monument: drain the Monument using Sponges, spawn-proof the surrounding area, and funnel Guardians into a kill chamber. A well-built Guardian farm produces hundreds of Prismarine Shards per hour passively. This is the only reliable method for players needing large quantities of Prismarine for big ocean-themed builds. See the mob farm guide for general farm design principles.

Craft Prismarine blocks and Sea Lanterns with your shards. Prismarine Shards are the core ingredient for all Prismarine crafting: Prismarine — 4 Shards in a 2×2 square = 1 Prismarine block. Prismarine Bricks — 9 Shards in a full 3×3 grid = 1 Prismarine Bricks block. Sea Lantern — 4 Prismarine Crystals + 5 Prismarine Shards (alternating in the grid) = 1 Sea Lantern (a light-level 15 underwater light source). Prismarine is one of the most visually distinct building blocks in the game — its animated texture slowly cycles through colours.

Drink Milk to remove Mining Fatigue before breaking Monument blocks: Elder Guardians inflict Mining Fatigue III on any player within 50 blocks, which makes breaking blocks extremely slow. Right-clicking a Milk Bucket clears all status effects including Mining Fatigue instantly — but the effect reapplies every 60 seconds as long as an Elder Guardian is alive nearby. Kill all 3 Elder Guardians first, then mine freely without the Milk Bucket dependency.
→
Looting III is essential for efficient Prismarine Shard farming: without Looting, each Guardian drops 0–2 shards (average 1). With Looting III, the maximum jumps to 4 shards per kill. Over hundreds of kills this makes a significant difference — enchant your Sword with Looting III at an Enchanting Table or Anvil before your Monument raid for maximum efficiency.

Ocean Monuments also contain 8 Gold Blocks hidden in the core room: inside every Ocean Monument, the central treasure chamber contains 8 Gold Blocks (72 Gold Ingots worth) hidden behind Dark Prismarine walls. After clearing the Elder Guardians, mine into the core of the Monument to find this hidden cache — a significant Gold bonus that makes Monument raids doubly rewarding alongside the Prismarine Shards.

Prismarine Shards and Crystals are different items — don’t confuse them: Prismarine Shards (from Guardian kills) are used for Prismarine blocks and Prismarine Bricks. Prismarine Crystals (also from Guardian kills, separate drop) are specifically needed for Sea Lanterns combined with Shards. Sea Lanterns are one of the few light sources that work fully underwater without being washed away, making Crystals valuable for ocean base lighting.

Wet Sponges from Elder Guardians speed up Monument draining massively: each of the 3 Elder Guardians drops 1 Wet Sponge on death. Smelt Wet Sponges in a Furnace to get dry Sponges, then use them to absorb large volumes of water inside the Monument quickly. A stack of Sponges can drain entire Monument rooms in seconds — far faster than bucket-by-bucket manual draining. This is critical if you plan to turn the Monument into an underwater base or Guardian farm.
Where do Prismarine Shards come from in Minecraft?
Prismarine Shards drop exclusively from Guardians and Elder Guardians — the hostile mobs that spawn inside and around Ocean Monuments in Deep Ocean biomes. Each Guardian drops 0–2 Shards (up to 4 with Looting III). There is no other source for Prismarine Shards in the game.
What are Prismarine Shards used for in Minecraft?
Prismarine Shards craft into three blocks: Prismarine (4 Shards = 1 block), Prismarine Bricks (9 Shards = 1 block), and Sea Lanterns (5 Shards + 4 Prismarine Crystals = 1 Sea Lantern). Sea Lanterns are level-15 light sources that work fully underwater, making them essential for ocean base lighting.
How do you find an Ocean Monument in Minecraft?
Use the command /locate structure monument (Java Edition) or /locate Monument (Bedrock Edition) for the fastest method. Without commands, explore Deep Ocean biomes — Monuments appear as large dark teal structures visible from the surface. Ocean Explorer Maps sold by Cartographer villagers also mark nearby monuments with an X.
What is the difference between Prismarine Shards and Prismarine Crystals?
Both drop from Guardians but serve different crafting purposes. Prismarine Shards are used to craft Prismarine and Prismarine Bricks blocks. Prismarine Crystals are specifically needed for Sea Lanterns (combined with Shards) and cannot be substituted. Sea Lanterns require 4 Crystals and 5 Shards each.
