We've burrowed deep down to within 10 blocks of bedrock to bring you this rare and precious mineral. Endowed with strong magnetic and conductive properties and a luminance of 9, you can now curl up in the warming glow of the Minecraft Light-Up Redstone Ore.
Sorry to break the mystique, but it's actually just made from rugged ABS plastic as opposed to carved from solid rock. And those are red LEDs glowing from within rather than priceless molten ore.
If you hit it with a pickaxe (enchanted with "Silk Touch" or otherwise) it will simply fall to pieces. But if you tap it gently with your hand it will begin to cycle through its three modes of brightness. The most cherished rock in all of Minecraft is now your very own soothing night light.
