Chiseled Quartz Block is a decorative variant of the block of quartz, featuring a carved pattern. It is commonly used in architectural designs and builds requiring a refined, elegant appearance.

It can be obtained by crafting two quartz slabs together or by using a stonecutter on a block of quartz. Chiseled quartz blocks cannot be reverted into their original components and can be used as a crafting ingredient for slabs and stairs. When placed under a note block, they produce a 'bass drum' sound.
