How to Get Heart of the Sea
There is only one way to obtain the Heart of the Sea in Minecraft, and that’s through Buried Treasure. Buried Treasure is very unlikely to be randomly stumbled upon, instead you’ll need to get your hands on a Buried Treasure Map.
When you open a Buried Treasure Map, you will see your own character indicated by a small triangular icon (or circle if you’re off the map). The location of the Buried Treasure is indicated by the red X icon.
You’ll want to craft a boat, and move around until you see your own icon getting closer to the X. Once there, it’s just a case of digging around until you find a Chest.
You should have no problem finding a Heart of the Sea, as it will spawn in 100% of Buried Treasure Chests. There is no other way to obtain the item, it can’t be traded with Villagers or crafted.
