The appearance of the Gelatin Crystal in-game.

The Gelatin Crystal is a Hardmode consumable item used to summon the Queen Slime boss. It can be found on Pearlstone, Pearlsand, or Pink Ice Blocks in the Underground Hallow. Upon breaking it, it drops the item used to summon the Queen Slime. It can be used at any time of day and any depth, as long as the player is in the Hallow.


  • When a Crystal Shard is to be generated, it has a 2*1/50 (2%) chance to generate a Gelatin Crystal instead.
  • The Gelatin Crystal glows pink and changes to blue and back in a cycle, which makes it stand out among the similar-looking Crystal Shards.
  • It can only be used in The Hallow. Attempting to use it in any other biome will have no effects, and will not consume the item.
  • The Gelatin Crystal will generate in worlds created prior to as well as after, so it is not necessary to create a new world to obtain it.


  • Similar to Crystal Shards, Gelatin Crystals can be quickly farmed by placing rows of Pearlstone Blocks, Pearlsand Blocks, or Pink Ice Blocks in straight lines in the Underground Hallow.


  • Unlike Plantera's Bulbs, another type of naturally spawning boss-summoning item, Gelatin Crystals' generation do not have a minimum distance restriction between each other. This can lead to two or more of them generating very close together.
  • Despite the difference, the Gelatin Crystal will be identified as a Crystal Shard by the minimap.


  • Desktop Can no longer be used to summon multiple Queen Slimes if one is already alive.
