▶ UnobtainableThe Heartstone is a block which was added during Valentine's Week 2013. Breaking one will drop a limited Valentine's item. Heartstones stopped spawning starting from 2016's Valentine's Week. Instead, 4 Golden Booty Chests spawn randomly in worlds with high-rarity items placed. They can still be made by spraying Love Potion #8 on Rocks, however. Breaking your first Heartstone or Golden Booty Chest will cause the player to earn the achievement Heartbreaker.
- The world needs to exist before Valentine's Week.
- The world must have a certain rarity. During the 2014 Valentines Event, a single row (100) of medium rarity farmables (e.g. Sugar Cane, Sharp Bass) could already yield you Heartstone Crystals.
- In 2016, the Heartstone was changed to where they no longer randomly spawn in worlds.
