Gullibulium

The rarest ore in a sandbox game called "Minecraft". This was a test ore that could be found in snapshot Beta 1.6.9, thought to be lost to history. Much like how emeralds are only found in mountain biomes, this ore is only in jungle biomes, even rarer. And even inside its own biome, it's still fifty times rarer than diamonds, some jungles having NONE. This is Gullibulium (Gulliblium), which was supposed to be the rarest material in Minecraft, until it got scrapped and later replaced by Netherite.

Gullibulium is also known as Gulliblium
