Power Gems Update
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Let's create a world just to find the new ores, blocks to build and much more, let's find the ruby, emerald set and the quartz one also, for an unbelieavable adventure. Travel, explore, search, craft, and don't forget to join... the nether.... for the new quartz variant and become immune to fire with the new quartz armor or get better prices from villagers! All this in the Power Gems Update, try it!!
