Nether Quartz is a mineral obtained by mining Nether Quartz ore in the Nether. Using a Fortune-enchanted pickaxe increases the amount of quartz dropped per block, making it an efficient resource to farm.

Nether Quartz is primarily used to craft redstone components, such as observers, comparators, and daylight detectors, which are essential for redstone circuits and automation. It is also used to craft quartz blocks, which are popular for decorative building due to their clean, white texture.
