This guide details how to obtain and utilize Prismatic Shards in Stardew Valley, updated for version 1.6. These rare, rainbow-colored gems are valuable for crafting, gifting, and completing quests.

Prismatic Shard Locations:
Several locations offer a chance to find Prismatic Shards, though the probability varies:
- Mines (Bottom): 0.05% chance of dropping from monsters.
- Fish Ponds (Rainbow Trout): 0.09% chance from a chum bucket (requires at least 9 Rainbow Trout).
- Skull Cavern: 0.1% chance from Serpents and Mummies (or Wilderness/Iridium Golems after Combat Level 10); 3.5% chance from Iridium Nodes; approximately 3.8% chance from Treasure Chests; 25% chance from Mystic Nodes.
- Omni Geode/Mystery Box: 0.4% chance inside.
- Golden Mystery Box: 0.79% chance inside.
- Volcano Dungeon: 3.5% chance from Iridium Nodes; one guaranteed in a chest upon first completion.
- Quarry: 3.5% chance from Iridium Nodes; 25% chance from Mystic Nodes.
- Meteorites: 25% chance to drop from a meteorite landing on your farm.

The most reliable method involves the Statue of True Perfection (obtained after achieving 100% Perfection). This statue yields one Prismatic Shard daily. See a separate guide for achieving 100% Perfection.
